See things more clearly with Alpine's 8" navigation receiver
I'm not really a "car guy," but I know plenty of them. And one thing I know is they like to stand out from the crowd. Alpine's X108U digital media receiver with built-in navigation lets you show off a big honkin' 8" touchscreen display for album info, maps, and even watching video when parked. That's a full 30% more screen area than standard 7" display offers. And this receiver's features turn it from just a brag-worthy piece of hardware to a high-performance media centerpiece.
How does it fit?
Alpine has developed a line of Restyle packages, each designed to accommodate the X108U in a specific vehicle. Every package contains a dash adapter which replaces a section of your dash, housing the Alpine receiver. Some packages also include wiring adapters that plug directly into the factory electronics and wiring, including the adapter that allows you to keep your steering wheel audio controls. Once you've identified your vehicle, you'll see if there's a Restyle package available.
No disc player? No problem
Since there's no disc player, the X108U's chassis is smaller than most comparable touchscreen navigators. It's likely to fit in more vehicles (including models for which no Restyle kit is available), and it should ease some of the frustration of installation since you'll have more room for wires, adapters, and other necessities behind the receiver in your dash opening.
You'll see your maps so easily on the 8" display, and you'll enjoy access to seven million points of interest and detailed road maps all across the entire U.S. and Canada. You'll also have time-saving aids like lane guidance, realistic views of complicated interchanges, and 3D representations of buildings, landmarks, and terrain to help keep you on the right path. You'll also receive real-time traffic reports in most metropolitan areas for as long as you own the stereo, at no additional cost.
Bluetooth® and quick access to your favorites
Built-in Bluetooth allows you to use the X108U for hands-free calling and music streaming through your compatible phone. The large touchscreen buttons for dialing and volume promote convenient operation. Alpine includes an external microphone to maximize the fidelity of your conversations.
The receiver's "Favorites" button gives you quick access to features you use frequently, like specific radio stations, phone numbers, destination searches, sound settings...anything you'll want to pull up instantly. One touch adds your choice directly to the favorites menu. Your favorites are tied to your phone's Bluetooth profile, so the X108U brings up your favorites automatically when you get into your vehicle. You can have up to two user profiles tied to the stereo, with up to 80 favorites per user spread across 10 touchscreen pages. When the stereo detects two users at the same time, it can offer split-screen access to both users' favorites, so either user can gain control of the action in a jiffy.
Fine functionality for your fingers
The X108U's 8" display features capacitive touchscreen control, similar to your smartphone or tablet. You can pinch-to-zoom the receiver's maps for a better view, or enlarge or shrink album artwork as you please with your fingers.
Not only does the X108U offer easy touchscreen access, it also offers dedicated hard keys along the bottom of the screen so you can quickly pull up functions like navigation, phone access, and sound settings without going through menu screens. You can create a custom top source banner that shows the audio sources you use most frequently, so you don't have to scroll anywhere to choose between a radio station, thumb drive, or MP3 player. The X108U also offers split-screen sound tuning, so you can adjust the sonic controls and change the tracks at the same time, for adjustments that don't waste time.
HD Radio™, Pandora® Internet radio, and more
The X108U comes ready to play with a plethora of entertainment options:
- HD Radio reception: You'll enjoy crystal-clear sound quality from participating AM and FM stations, including FM that sounds almost as good as a CD. Plus, you'll see station and song info on the screen.
- Pandora Internet radio: Pandora lovers will love touchscreen control over their stations, including thumbs up and down, bookmarks, and station lists. Just plug your iPhone® into the USB port or use Bluetooth audio with your Android™ device.
- iPhone and iPod® control: Browsing for your favorite songs is simple and concise, thanks to an intuitive touchscreen interface and the huge display. You can check out song title, artist info, and album art with a quick glance at the big screen.
- Satellite radio compatibility: You can add SiriusXM programming to the receiver with an optional tuner and your paid subscription.
Hook it up
The X108U also features an HDMI input, allowing you to connect most compatible Android smartphones and devices. With the correct HDMI or MHL cable connected, you'll be able to view video content from your phone or a portable Blu-ray Disc™ player on the Alpine's screen while parked. You can also connect to compatible rear-seat screens via HDMI cable to play digital video files for your passengers. You also get a rear USB port, plus a rear A/V input.
You can also connect up to three cameras with the optional Multi-Camera Selector Interface, so you can see more of what's around your vehicle when getting in and out of tight spots. Dual-zone output means your back-seat passengers can enjoy movies on optional video monitors while you enjoy some music up front. If you're looking to add subs and amps, you can take advantage of three sets of high-voltage preamp outputs.
Play with your toy's coolest features
If you've loaded your vehicle with add-ons, the X108U's got you covered. The optional Accessory Control Module enables simple system expansion, allowing touchscreen command of up to 8 electrical devices like winches, LED lights, interior lights, suspension kits, and powered bed covers. It'll even let you control your compatible truck toolbox lock remotely. You can customize the onscreen icons and button labels, so you'll be able to access your devices with ease.
Enhanced sonic controls
Alpine's audio engineers have loaded special Sound Parameters Settings into this receiver for all the vehicles covered by Restyle packages. You pick the one that matches your vehicle to get sound that's custom-EQ'd and time-corrected for your vehicle's acoustics. Tailored sound, no tweaking required.
The X108U also works with Alpine's TuneIt 2.0 smartphone app, which is a real time-saver for making audio fixes. For starters, it allows you to create a user profile with info about your vehicle and Alpine system, including speakers and subs. You can then follow simple instructions for adjusting sound settings for your specific vehicle (if available), or choose from pre-made settings within the app designed by Alpine for both the vehicle and your speakers.
You can use your phone's touchscreen to make the changes to the 9-band parametric equalizer, crossover, and time correction with just a fingertip. You can then share your system and settings with other TuneIt app users, and see what they've done as well. You can link your TuneIt account to your Facebook account and get notifications through social media.
The X108U boasts front and rear independent EQs, so you can fine-tune the audio for each listening position in your vehicle. The TuneIt 2.0 app also offers Alpine's Bass Engine SQ tuning feature, which lets you determine which low-frequency characteristics you want to emphasize. It automatically adjusts EQ, sub level, and crossover settings to give you the kind of bass you desire without hassle.
And speaking of great sound, this Alpine lets you play FLAC audio files from your thumb drive, so you can enjoy your lossless tunes as you travel.
Siri® Eyes Free for non-distracting operation
This receiver supports Siri Eyes Free for iPhone users, which means you can ask Siri to make calls, select and play music, compose and hear text messages, read notifications, even use maps and get directions — all commanded by your voice through your Alpine receiver, without any visual distractions from your Apple® device.
Want to keep your car's steering wheel audio controls?
In most cars, you'll need an adapter to retain those controls with this car stereo. Connect a few wires, then program the adapter for your particular car and radio, and you'll retain the convenience of your steering wheel controls. You'll see the adapters that work with your vehicle when you add this receiver to your cart.
iDatalink Maestro lets you keep your car's factory extras
If your vehicle comes with factory add-ons like Ford SYNC®, GM OnStar®, Chrysler Uconnect™, or Volkswagen Bluetooth, you don't have to worry about losing your favorite conveniences to get navigation and better sound — the X108U offers compatibility you won't find in many other aftermarket radios, thanks to the iDatalink Maestro module (not included).
- For Ford SYNC systems, you'll be able to retain voice-controlled features, steering wheel audio controls, and factory audio functions;
- For GM vehicles, you'll keep your steering wheel audio controls, your factory amp, safety warning chimes, and OnStar, if present;
- Chrysler owners, you'll get to keep all your Uconnect functionality;
- Toyota: you'll keep your factory amplifer, auxiliary and USB inputs, rear-view camera, and steering wheel audio controls
- VW owners: you'll keep your factory Bluetooth amplifier and fader, plus the use of the factory media device interface.
The iDatalink Maestro also works with the X108U to provide access to extra features, including climate controls, vehicle info (door status, tire pressure, read and reset engine codes), and gauges (speed, boost, turbo, RPM, engine temperature, and more) through the receiver's touchscreen.
What if there's no Restyle package for my vehicle?
If there isn't a Restyle. package available for your vehicle, Alpine offers their KTX-UTB8 universal dash bezel for custom installations. In most vehicles not covered by Restyle, you can use an adapter to connect your vehicle's steering wheel controls to this Alpine stereo, too.

Alpine X108U reviews
It was quite the decision with weeks of research deciding to upgrade my audio profile on my 2015 GMC truck. Being a true audiophile I desperately needed a system to replace the factory OEM set up but needed to be extremely cautious so not to compromise the comprehensive built-in electrical system on my vehicle. After consulting with multiple audio technicians including GMC's provider ACDELCO I became a bit frustrated due to conflicting information regarding compatibility and functionality. A well-deserved ovation and thankyou to Crutchfield and their "Ask an expert" team for having the ability to provide 100% accurate information regarding proper fit, compatibility and spec data that I required. Crutchfield provided me with the utmost professionalism and more importantly curtesy. The Alpine X801U is nothing less than a piece of art that will meet and or exceed any audiophiles needs. The technology and user interface is well thought out and the sound can only be described as the finest of silks and champagne to the ears. Thankyou Crutchfield and the "Ask an expert" crew for helping me with my system build out.
Pros: #1 - Sound quality #2 - Incredibly intuitive and easy to manage interface #3 - Great Nav system compared to "the other guys" #4 - Bluetooth and Smartphone connectivity seamless
Cons: I couldn't thank the Crutchfield team in person

Nice unit looks great
Pros: Love the large touch screen, navigation is sweet compared to company standard in vehicle. I was able to install it my self with some help from Crutchfield technical support team one of my many reasons for purchasing from Crutchfield. Sounds Great as well after downloading the Tuneit App.
Cons: There is no dash kit for my 2002 Acura RL, will have to pay more to make my install look Professional and unless you really understand how to manually tune and radio it is very challenging however downloading the Tuneit App simplify it just be careful of downloading one of the shared tunes this will change the opening look of your unit and so far I can't figure out how to change it back.

Great Unit and perfect fit for my 06 F-150. If your looking for a unit with all of the bells and whistles as the newer vehicles come with these days then this is it. To my surprise it also has "switches" built into the unit for controlling light bars, etc. This unit is top of the line. I installed this myself with the help of Crutchfield's installation gear and 1 phone call to tech support.
Pros: Everything about the radio.
Cons: None yet.

8" Touchscreen Display: The Alpine X108U has a 8" WVGA (1.15 million-pixel) touchscreen LCD monitor (with 16:9 aspect ratio) that serves as a video monitor, information display, and system controller. The X108U's touchscreen monitor provides a more balanced picture, not over-emphasizing dark or light areas, so album art, map screens, and video are seen with greater clarity. All of the graphics & icons are crisp and clean for your viewing pleasure.
- Dual Screen: The Alpine X108U lets you display the Navigation and Audio/Visual screens simultaneously, side-by-side. You can switch the right and left screens using simple drag & drop touchscreen commands.
- My Favorite Shortcut Screens: The "My Favorites" feature lets you customize quick-access screens with up to 54 shortcuts to your most-used features. You can design as many as 6 "Favorites" page profiles with eight shortcuts per page. Shortcuts can be created from audio sources, navigation commands (favorite places/direct search/nearest POI search), and phone settings (favorite contact/direct call). The shortcuts are easily added by pressing the shortcut soft key that appears within all audio and hands-free sources. Your settings are kept as a personal profile linked to your smartphone via Bluetooth.
- Clock Display: The X108U lets you select between a 12 hour or 24 hour clock. The clock is displayed on each source screen and turns off when the head unit is powered down. Once you have launched and accepted navigation mode, the unit's clock syncs up with the internal navigation system, so it automatically adjusts to your time based on your location. Whether you are in Hawaii or New York, the X108U will adjust and display the appropriate time.
Note: For safety and legal reasons, the Alpine receiver features a video lock-out feature to prevent the driver from viewing a video source while the vehicle is in motion. To watch a video source, the vehicle must be stopped with the parking brake engaged and the ignition in the ACC or ON position. This also includes advanced setup menus. This also pertains to the receiver's System, Audio/Video, & Navigation Setup Menus.
Perfect F.I.T. Design: Because of its large 8" touchscreen LCD monitor, the X108U will not fit a standard Single-DIN or Double-DIN dash opening. To accommodate this large screen in your vehicle's dash, Alpine offers a line of Perfect Factory Integration Technology (F.I.T.) packages specifically for the X108U. Alpine's Perfect F.I.T. installation packages allow the X108U to fit seamlessly into select vehicle dashes. Perfect F.I.T. is designed to cosmetically match the shape, color and texture of the vehicle's interior. The Perfect F.I.T. installation package come with all necessary accessories for the installation of the X108U, including an Alpine/vehicle-specific harness, antenna adapter, Alpine-specific steering wheel interface, and BUS adapter (if necessary). A variety of new kits, representing popular U.S. vehicles, are available (all sold separately).
Note: As always, please consult Crutchfield's Outfit My Car to verify fit with your vehicle.
Start Up Time: The Alpine X108U has a start up time of approximately 5.51 seconds from Off to the Navigation or AV source screen.
Display Settings: The Alpine X108U offers the following settings to customize the head unit's LCD touchscreen monitor.
- Display Colors & Custom Start Up Image: You can choose from eight different background colors for the display; Blue, Light Blue, Aqua, Red, Green, Amber, Yellow, or White. You can even use a BMP image (800 x 480) that is stored on a USB thumbdrive as the head unit's opening screen.
- Display Modes: You can select one of the following display modes - Wide (evenly stretches a 4:3 picture horizontally to fit the widescreen monitor), Cinema (displays a 4:3 picture by stretching out the picture horizontally and vertically), or Normal (displays a normal picture at the center of the screen with vertical black bands on each side).
- Visual EQ Mode: You can select one of the following preset modes suitable for the video image - Off (initial setting), Night (suitable for movies with dark scenes), Soft (suitable for animated films), Sharp (suitable for old movies with less clarity), or Contrast (suitable for recent movies). You can also create two custom presets by manually adjusting the monitors Brightness, Color, Tint, Contrast, and Sharpness.
- Backlight Control: You adjust the brightness of the LCD backlight from -15 to +15. You can then select one of the following modes for the LCD's fluorescent backlight - Auto (adjusts the brightness of the background illumination based on the ambient light in your vehicle), On (keeps the background illumination of the monitor dark), or Off (keeps the background illumination of the monitor bright).
Note: You can also turn the touchscreen completely off at night, if the display is too bright when simply listening to audio and have no need for a monitor display.
Hard-Key Controls w/ Variable Color Illumination: In addition to the touchscreen controls, the unit includes frequently used buttons along the bottom-edge of the screen. You can adjust the color illumination of the head unit's hard-key buttons from Blue, Light Blue, Aqua, Red, Green, Yellow, or Amber. You can also adjust the brightness of the button lighting at night from -2 to +2.
Remote Control: The Alpine X108U offers compatibility with factory steering wheel controls (adapter sold separately) and supports Alpine's IR wireless remote control (sold separately) for added convenience.
- Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input on the rear of the unit that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately). Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.
- Optional Wireless Remote: The Alpine X108U is wireless remote control ready. Simply add on the Alpine RUE-4202 IR remote (500RU4202, sold separately) to make it even easier to control the head unit's basic tuner & playback functions. The remote does not offer navigation control.
HERE Map Data: The Alpine X108U offers reliable navigation with preloaded HERE map data of the United States and Canada, including Alaska, Hawaii, Puerto Rico, and the Virgin Islands. The map database provides approximately 7 million points-of-interest (POIs) in various categories throughout the coverage area. The unit's map data is stored its built-in flash memory.
Note: While this receiver's map database was judged to be as accurate as possible at the time of its release, a map database can never be 100% accurate. Road information that is maintained in the map databases, such as turn restrictions or road names may change over time.
Future Updates: Future Map and Software updates (purchase fees will apply) will be available periodically and are input using the unit's USB port and a USB thumbdrive (sold separately). For updates and add-on options, please visit www.naviextras.com (requires Windows XP or newer; not compatible with Mac). A free program called "Toolbox" can be downloaded from this website so you can create a copy of your map as a backup, as well as assist in easily checking for updates and optional features that are available.
GPS Receiver & Antenna: The Alpine X108U features a built-in GPS receiver and includes an external GPS antenna which determines vehicle speed and heading changes, along with longitude and latitude information, to accurately determine vehicle heading and position on the system's digital map. The GPS antenna can be mounted inside or outside of the vehicle. The GPS antenna measures 1.0625" (w) x 0.5" (h) x 1.1875" (d); with a 11.5' cable.
Note: The navigation receiver took approximately 19.5 seconds to calculate directions from Virginia to California. It took approximately 7.4 seconds to calculate directions from Virginia to Maryland. These tests were done inside the Crutchfield Lab of the Crutchfield Head Quarters. Results will vary based on length of calculated route and your surrounding area.
On-Screen Map: As you travel, the X108U guides you to your destination via its on-screen map. The unit's on-screen map shows your vehicle's current position (a blue arrow by default), the recommended route (an orange line), the surrounding map area, and your destination as a checkered flag. The on-screen map shows streets in a way that is similar to how the paper road maps show them. Their width and colors correspond to their importance; you can easily tell a freeway from a small street. Road segments affected by traffic events are displayed with an alternate color on the map, and small symbols above the road show the nature of the event. When navigating a route, the top section of the map screen shows information about the next route event (maneuver) and the next street or the next city/town. Both the type of the event (turn, traffic circle, exiting freeway, etc.) and its distance from the current position are displayed. When approaching a turn, the map screen will zoom in and raise the view angle to let you easily recognize your maneuver at the next junction. If the next turn is at a distance, it will zoom out and lower the view angle to be flat so you can see the road in front of you. Two data fields on the left of the screen shows the distance you need to travel on the route before reaching your final destination and the time needed to reach your final destination of the route based on information available for the remaining segments of the route. You can adjust the following map settings.
- Map Views (2D/3D): The X108U provides three Map
Views, choose from North Up (North is always at the top of the display;
this makes it easy to determine your current heading with respect to the map), Heading
Up (current direction is always pointing to the top of the display; this
makes it easy to see the direction of the next turn on the map), or 3D View
(more realistic perspective by tilting the map and displaying it with a
horizon line; streets are displayed as you approach them instead of from a
birds-eye view). The X108U's navigation software supports
the following 3D object types.
- 3D Terrain: 3D terrain map data shows changes in terrain, elevations or depressions in the land when you view the map in 2D, and use it to plot the route map in 3D when you navigate. Hills and mountains are shown in the background of the 3D map.
- Elevated Roads: Complex intersections and vertically isolated roads (such as overpasses or bridges) are displayed in 3D.
- 3D Landmarks: Landmarks are 3D artistic or block representations of prominent or well-known objects.
- 3D Buildings: 3D block representation of full city building data containing actual building size and position on the map.
- Map Color: The navigation map screen uses different color themes (Day/Night) during the day and during the night for both the map and the menu screen. Daytime colors are similar to paper road maps, and the menus are bright. The night color themes use dark colors for large objects to keep the average brightness of the screen low. You can also set the navigation unit to switch between daytime and night color modes automatically based on the current time and GPS position.
Note: Alpine's Dual Screen function lets you view Navigation and Audio/Visual screens simultaneously, side-by-side.
Highway Driver Assistance: The X108U's navigation map offers helpful lane information & signpost guidance, along with junction & tunnel views, plus exit services for highway drivers.
- Lane Information: When navigation on multilane roads, it is important to take the appropriate lane in order to follow the recommended route. If lane information is available in the map data, the map screen will display the lanes and their directions using small arrows at the bottom of the map. High lighted arrows represent the lanes you need to take.
- Signposts: Where additional information is available, signposts substitute arrows. Signposts are displayed at the top of the map. The color and style of the signposts are similar to the real ones you can see above the road or by the roadside, They show the available destinations and the number of the road the lane leads to.
- Junction & Tunnel View: If you are approaching a freeway exit or a complex intersection and the needed information exists, the map is replaced with a 3D view of the junction. The lanes you need to take are displayed with arrows. Signposts can also be present, if information is available. When entering a tunnel, the map is replaced with a generic tunnel image so that surface roads and buildings cannot distract you.
- Exit Services: The Exit Services function lets you search roadway exits for food, lodging, and rest areas so you are never left guessing what is around the bend. You must be on a major highway or road to use this feature.
Voice Guidance w/ Text-to-Speech: In addition to graphical on-screen directions and maps, the X108U provides voice guidance and turn-by-turn directions, capable of text-to-speech (TTS), announcing the street names along with the turn directions. With turn-by-turn instructions delivered by Text-to-Speech (TTS) technology, street names, freeway numbers and freeway exit names are announced clearly through your vehicle's audio system. Directions are available in English, Spanish, or French.
Note: The X108U will mute the audio source, when there is a text-to-speech voice prompt. Once the voice prompt has ended, your audio source's volume will automatically raise to previous setting.
Traffic Message Channel (TMC): The Alpine X108U contains a TMC (Traffic Message Channel) receiver that can provide you with the real-time status of the traffic along your route over the FM Radio Data System (RDS). If traffic is congested up ahead or there is a road closure, the navigation system will automatically re-navigate the route to show you how to get to your destination, quickly and easily. To fine-tune this recalculation, you can set the minimum delay that can trigger a route recalculation, or you can instruct the software to have you confirm the new recommended route before it takes effect. Road segments affected by traffic events are displayed with an alternate color on the map, and small symbols above the road show the nature of the event.
Note: TMC is not available in all cities.
Where AM I?: The "Where Am I?" screen contains information about the current position (or approximately the last known position if GPS reception is not available) and a button to search for POIs and emergency services nearby.
Selecting A Destination: The built-in navigation software offers you several ways of choosing your destination.
- Free-Form Search: A quick way to search for an address, a Place, an Address Book entry, or a History item is to use the free-form search. Simply enter a street address (just the street name or both the street and the house number), the name of a Place, a previous destination or an Address Book entry from this one search screen.
- Browse Map: Select a location on the map by simply tapping the map.
- Address: You can find an address by entering the exact address (including house number), the center of a city/town, an intersection, the midpoint of a street, or zip code.
- Address Book: Save frequented locations in the unit's address book to quickly add as a destination (like your home or office).
- Places (POI): Select from approximately 7 million Point-of-Interests (POIs); search POIs by name, preset, or category around your current location, destination, route, or specific city.
- History: Destinations you have set previously appear in the History search.
- Coordinates: Enter Latitude and Longitude coordinates as your destination.
Note: Any destination selection method can be entered with or without the parking brake engaged.
Vehicle Profile: You can create a vehicle profile for your car, truck, or SUV. Enter the following parameters for your vehicle - Fuel Consumption (avg. fuel consumption of your vehicle in city and rural areas), Engine Type (engine and fuel type), Fuel Price (avg. fuel price for travel cost calculation), Max Speed (max speed you travel).
Route Calculation: The unit's navigation software calculates your route based on the following selections.
- Vehicle Types: You can select what type of vehicle you are driving, so the navigation unit can determine the best route based on your vehicle type (Car, Truck, Emergency, Bus, or Taxi).
- Route Methods: You can choose which route method
(Fastest, Shortest, Green, or Easy) the navigation unit should use when
calculating your route.
- Fast: Gives a quick route if you can travel at or near the speed limit on all roads. Usually the best selection for fast and normal cars.
- Short: Gives a route that has the smallest total distance of all possible routes. It can be practical for slow vehicles.
- Green: Gives a quick and fuel efficient route based on the fuel consumption data given in Route settings. Travel cost and CO2 emission calculations are estimations only. They cannot take elevations, curves and traffic conditions into account.
- Easy: Results in a route with fewer turns and no difficult maneuvers. With this option, you can make your software to take, for example, the freeway instead of a series of smaller roads or streets.
- Avoidances: You can tell the navigation unit to avoid certain types of roads along your calculated route, such as Highways, Tolls, Carpool/HOV, Unpaved Roads, and/or Ferries.
Modifying Your Route: When navigation is already started, there are several ways to modify the active route. Options include:
- Add Waypoint: If you already have a recommended route and you select a new destination, the unit will ask you whether to start a new route, add a new waypoint (intermediate destination) to the route or append the newly selected destination at the end of the current route.
- New Starting Position: For normal navigation, all routes are planned from the current position.

Beep Guide: This function will give audible feedback with varying tones depending upon the button pressed. The volume of this feature can be set from 0-7.
Audio/Video Input: The Alpine X108U is fitted with one rear-panel AV minijack (3.5mm) input to connect an external AV source.
HDMI Input: In addition iPhone and Android connectivity, the head unit's HDMI input can be used to connect almost any external mobile AV source with an HDMI output, such as Alpine's DVE-5300 DVD player (500DVE5300; sold separately). The HDMI input will provide video and audio playback. Your vehicle's parking brake will need to be engaged to view video on the receiver's screen. Playback functions will need to be controlled from your HDMI-connected device, unless you are connecting the DVE-5300 DVD player which does allow control from the X108U's touchscreen. The HDMI input support video resolutions up to 480p.
Note: If you need more than one HDMI input, you can purchase Alpine's HDMI switcher (500KCX630H, sold separately), which provides a total of two HDMI inputs and one HDMI output.
HDMI Output (w/ Dual Zone): The X108U is equipped with an HDMI monitor output for rear seat entertainment (RSE). The rear seat entertainment function independently routes a different source to the front and rear of the vehicle. For example, while listening to the head unit's built-in HD radio or other audio source in the front, HDMI can be enjoyed in the rear with optional rear monitors (featuring an HDMI input) and headphones. The unit's HDMI input is the only source that can be displayed in in the rear through the head unit's HDMI output. The HDMI output supports video resolution up to 480p. The parking brake does not need to be engaged to enjoy HDMI playback in the rear of the vehicle.
Camera Input: The X108U features a proprietary camera input for connecting one of Alpine's proprietary backup cameras (sold separately). There is also a composite video rearview camera adapter which allows you to connect almost any camera with a composite video connector, like Alpine's Alpine HCE-C125 camera (500HCEC125, sold separately). You can only use one or the other; you cannot use both types of camera inputs. In order to connect two cameras to receiver, you will need Alpine's KCX-C250MC Multi-Camera Selector Interface (500KCXC250, sold separately), which only works with the Alpine's proprietary cameras (sold separately).
- Multi-View: The X108U's camera input can be set as a Rear camera, Front camera, or Side camera.
- Guidelines: The rear-view camera function also provides on-screen color-coded guidelines to assist you when backing up your vehicle into a parking space. There is also a Hitch Guide feature which marks the position of the junction between your vehicle and your trailer on the head unit's monitor, when backing up.
- Backup Auto Switching: If a rear-view camera is connected, you should also connect the unit's reverse lead wire (Orange/white) to your vehicle's back-up lamp circuit. When properly connected, the image from the rear-view camera automatically appears on the monitor when the vehicle is shifted into reverse. Automatic video switching takes approximately 0.75 seconds. Audio from your music source will continue playing, while the back-up camera is displayed.
Note: The rear view camera feature is meant as a back-up aid only; never solely rely on the rear-view camera when backing-up. In addition to using the rear-view camera, always look behind you to make sure everything is clear when backing up your vehicle.
iDatalink Serial Port: This Alpine navigation receiver is compatible with the iDatalink Maestro RR (794ADSMRR, sold separately); a web programmable module that will permit the aftermarket Alpine receiver to work with select Ford, Lincoln, and Mercury vehicles that feature the factory SYNC system; as well as select GM vehicles with factory OnStar; select Chrysler/Dodge/Jeep vehicles with U-Connect, and select Volkswagens with factory digital amplifier.
- Retained Features: The iDatalink Maestro RR lets Ford/Lincoln/Mercury, GM, Dodge/Chrysler, and VW owners swap out their factory radio for this aftermarket Alpine head unit; while retaining the Ford Sync system, GM OnStar system, Chrysler/Dodge/Jeep U-Connect system, steering wheel controls, Bluetooth, USB interface, Satellite Radio, and 911 assist. You also get to keep the hands-free mic that comes with the car (which is specially tuned to that particular vehicle). *Retained features will vary by vehicle.
- Extra Features: In some installations, the iDatalink Maestro RR lets you configure the head unit to operate interior climate controls and provides extra visual data; such as User Selectable Gauges, Vehicle Info (Tire Pressure/Battery Voltage/Check Engine Codes/Door Ajar Warning), and Visual Park Assist. *Extra features will vary by vehicle.
Note: The iDatalink Maestro RR is web programmable, which means you'll need to flash the iDatalink Maestro RR interface module with the correct firmware from iDatalink's website. In addition to flashing the iDatalink Maestro RR module, you'll also need a vehicle specific harness (sold separately). The Alpine receiver's OEM Setup menu must also be configured with your compatible vehicle's factory system before initial operation.
