    Easy install and great sound

    Julio from Marietta, GA on 11/24/2016

    Crutchfield Customer Review (What's this?)

    Installed in a 2000 Jeep Grand Cherokee where the stock radio had a ton of static and CD player was not working. This unit solved all these problems, looks great and the sound is perfect! The adapter kit with the head unit made installation a breeze. I highly recommend for someone who just needs to upgrade their radio without busting the bank.

    Pros: Great sound, front USB attachment for pandora or any other iPhone music, easy install

    Cons: None so far

    This radio was easy to install very easy to operate

    Pros: Fantastic lights,alot of options excellent sound with easy adjustments of the equalizer.

    Cons: To turn up the volume when on the move too easy to press the volume control rather just turn it.

    Crutchfield Customer Review (What's this?)

    First off I ordered the wrong setup, but got great support getting the right parts. Their service is amazing! A person answers right away who speaks English and knows about car stereos. I got my questions answered quickly and smartly, with a little bit of southern charm. The radio is perfect! I couldn't be happier!! I have seen people complain about the face being too bright at night. There is a day and night setting on the radio. FYI. Initially I got no sound, but a call to cust service gave me the solution. I had to put a couple wires together not mentioned in the instructions, but it was no big deal. My truck is 20 years old, so I wasn't too surprised. If you run into trouble, just call. There are plenty of online videos on putting in stereos and I got a good deal of info from them and the products sent me by Crutchfield.

    Pros: Looks, sound, price, service

    Cons: Can't think of any..

    Great stereo to replace factory radio

    Pros: Easy installation, great product, nice sound, great FM reception. Due to it's great sounds, getting ready to order a 3rd one.

    Cons: The only con, is instruction on how to set up display, sound, etc are rather vague. However after calling technical support I was on my way to enjoying my new stereo.

    This is the second one of these same radio's I've bought in last six months. Put one in my 95 Chevy truck and one in a 03 Malibu. Definately sounds better in the Malibu!!! Overall a great radio with all the features you need these days.

    Pros: Tons of features for the price.

    Cons: A tad confusing navigating thru all the set-up features- even with the manual sitting there. But once done I have no complaints.

    Great product

    Ryan M from Tucson, AZ on 7/3/2016

    1994 Toyota Corolla
    Crutchfield Customer Review (What's this?)

    My stock unit finally gave out, so I bough this radio as a replacement and so far I've been very pleased. The build quality is exceptional and the sound is much better than the stock unit. I do have some minor complaints, though. It is a VERY tight fit in my corolla, so I was unable to install the protective bracket around the radio and the head unit itself was very difficult to attach to the body of the radio. Additionally, the screen can be very hard to see dieing the day but this may just be a local problem as I do live in a very sunny location. Everything else about the radio is wonderful. I love that I can charge my phone through the usb port, I love how it looks in the dash, it's amazing that I can set the colors to anything of my choosing and the dimmer option is extremely helpful for night driving. I would definitely recommend this radio as a replacement to a friend.

    Pros: Look Build quality Color options USB charging Dimmer Sound quality

    Cons: Extremely right fit Difficult to read display during daylight

    Great improvent

    Sony CDX-G3100UP Car Stereo Review

    steve from San Bernardino, CA on 5/7/2016

    2001 Toyota Tundra
    Crutchfield Customer Review (What's this?)

    This unit was used to replace an older Sony CD unit. This one sounds as good or a bit better. It has more EQ frequencies (5) to set and that is most of it. The menu structure is the same as my older one, so it wasn't hard to adapt to this one. If you're not familiar with the way the button pushes work through the menus though, you may "get lost" in them at first. Fortunately it doesn't take long to get up to speed. This is the only reason for 3 stars for ease of use. I enjoy CDs still, but I mainly wanted the USB input. I can rip the CDs into WMA or MP3s in media player, and put them on a jumpdrive. Voila! No worry about dirty CDs skipping or needing to be changed. The sound quality is very nearly indistinguishable from CD (we're talking about car audio here - not generally Hi-Fi enough to tell the loss of resolution, especially in a moving vehicle from a <$100 unit). I would not hesitate to buy again!

    Pros: Excellent for price, good sound, combination of features, Very Customizable

    Cons: So customizable that the menu structure to do so may be a bit vexing, until you get used to it!

    Steve from walnut creek, CA on 2/9/2016

    2010 Toyota RAV4
    Crutchfield Customer Review (What's this?)

    Having bought a lot of Sony products, I was expecting more. I selected this particular unit because of the specs on the FM receiver (I listen to a lot of FM). According to the numbers it should perform substantially better than both the competitor's products and the unit I was replacing. Wrong. It is clearly worse than what I replaced. FM fades quickly when signal should be more than adequate. Noisy as well. Really disappointing. Amp power is adequate but not impressive. Overall operation of the unit is non-intuitive. Channel seek is particularly frustrating. Unless you like the disco light display that is the default setting, I would pass.

    Pros: Straightforward installation, supplied instructions adequate for the job, but I suggest checking out additional videos or written instructions before disassembling the RAV4 radio. Impressed that all of the wiring colors matched the supplied mating harness. Assembled replacement for the RAV4 dashboard looks good. Aux in works, replaces the disconnected Aux In on the RAV4 between the seat console (that will no longer function).

    Cons: A few of the dash install parts were somewhat confusing / difficult to assemble. Lack of instructions on where certain mounting screws should go. Relatively poor FM reception, confusing unit operation, very small buttons/controls on the unit, somewhat under-powered.

    I bought this stereo for my daughter's car. It was very easy to install and she loves the sound. She also loves the AUX and Bass Boost. I only gave 4 stars on the build quality because it is still new and we will see how long it lasts.

    Pros: Price, ease of installation, and sound

    Cons: None so far.

    Crutchfield Customer Review (What's this?)

    Buying through Crutchfield eliminated the hassle of going to the store, searching for the appropriate harness and bracket. On top of that, it was probably the easiest install I've done out of the 10 I've done so far. So easy, my buddy actually watched and loved the quality of it, he went out and got one too! Love this product.

    Pros: Clear instructions Quick and easy- was done in 30 minutes! Great quality radio Impressive features including the Mega Bass, and the fact it pushes 55w to my new speakers!

    Cons: If you've never put one in, could be a little complicated, but it's not Rocket science, you'll get it quick.

    This head unit is a great value and gave me a lot of bang for the buck. Under $100 and easy to install. Sounds great, looks great and Sony quality throughout. Recommended if you want a good stereo for low cost.

    Pros: Sound quality, RCA preamp and sub outputs, iPod control, high output.

    Cons: Display colors are changeable but I just use white.

    Sony CDX-G3100UP vs. Sony CDX-GT660UP

    InfectiousAgent from North Dakota on 12/7/2015

    2003 Dodge Durango
    Crutchfield Customer Review (What's this?)

    Installed on a 2002 Dodge Durango w/ Infinity System. Replaced Head-Unit and bypassed the factory amp. Speakers: JL Audio TR-650csi (no amp). Overall: Good Head-Unit but lacks "Wow Factor" When compared to the Sony CDX-GT660UP set up identically in my 2003 Dodge Durango, the Sony CDX-G3100UP lacks the tuning ability to truly "dial in" the JL Audio TR-650csi's. Even with the new "MAGABASS" feature, the difference in both clarity and loudness is noticeable when comparing the two systems side by side.

    Pros: Sony! Looks Awesome! Great build quality! Easy install.

    Cons: Compared to the discontinued Sony CDX-GT660UP, the Sony CDX-G3100UP is somewhat lacking.

    Love This Radio

    TomT from Virginia on 11/16/2015

    I bought this unit to replace my Dodge Dakota radio that died. It has great sound and many extra features not available on factory unit. I love the lighted dial, USB port and remote control. It was easy to install and everything worked correctly. Installation kit made the job easy.

    Pros: Great sound, looks good in dash, installation kit, and remote control.

    Cons: Push buttons are a little small for me to see without my glasses (age related).

    Very excellent head unit for the price from Crutchfield, Especially since you get the install kit, wire harness, instructions, And a 2 month free Pandora One subscription. (At least I got that). Im coming from a Kenwood head unit, and you could set the volume louder if that makes sense, cannot do that one this one, at least not that I have found. That is my Only complaint. Lovin' it! It was the first thing I did to my new car.

    Pros: I received this a day early and it was exactly as described. I will order again! I am so pleased.

    Cons: It took me a little bit to figure how everything worked and set it up the way I wanted. I played with it for about an hour, and it's good to go now!

    Excellent value

    EJ from Minnesota on 11/9/2015

    1996 Ford Explorer
    Crutchfield Customer Review (What's this?)

    Great sounding unit when paired with efficient speakers. I used 4 6x8 Infinity speakers rated at 2 ohms and the sound quality is very good. Way better than expected. I tossed in a Powerbass sub to round out the low end and am very happy considering that I really haven't spent that much overall. The factory stereo is a distant, bad memory.

    Pros: Respectable sound quality, amp ratings are accurate and not exaggerated. Price is right. Looks nice.

    Cons: I wish there where actual physical controls for bass and treble instead of having to focus attention on pushing buttons through menus to make sound adjustments.

    Excellent upgrade from factory system

    BobC from Maryland on 11/6/2015

    2001 Volvo S40
    Crutchfield Customer Review (What's this?)

    This sounds much better than the 15-year-old head unit it was replacing and has a more intuitive control layout than most comparable units I've seen. My few complaints are minor - the factory provided colors settings are poor (but you can create your own), it's almost impossible to read the display when it scrolls information (which also makes it difficult to see the selection when changing modes because of a completely unnecessary scroll which takes place almost immediately after changing modes) and it ignores sub-folders on thumb drives making it impossible to organize those files in any way other than by album. Another plus from Crutchfield is that it arrived the day after I ordered it even with free shipping! The installation was quick and easy, although there was no warning that I'd have to strip some wires and buy the crimp caps necessary to connect them to the adapter. The hardware for turning the second DIN slot into a storage space didn't fit properly, but it's hard for me to complain about that since it was provided for free.

    Pros: Sounds great Easy to install

    Cons: information display could be improved no way to organize files on thumb drive

    Crutchfield Customer Review (What's this?)

    This player is an awesome little unit that is practical and easy to install with the kit provided by Crutchfield. It plays CDs, MP3, Pandora from your mobile unit, etc. The display will change colors to suit your taste, and the sound quality is adjustable through various presets along with a custom setting. The front display face is removable for added security. Awesome product from an awesome company!

    Pros: Product is everything the advertisements say that it is; however, the kit with dash box, wire harness, and wire ties makes it so much easier to navigate the installation. Definitely worth NOT having the hassle of a bad installation.

    Cons: None! It even shipped and was received on time for early installation.

    Needed to replace the factory CD player in my car. This does exactly what I want, while adding a few more options that are really nice (USB port). Love the colors on it! Was simple to install and looks really cool! Only problem I have is the face plate does not easily attach or detach, but since I don't necessarily plan on taking it off regularly, it is not a problem.

    Pros: Simple to install, sounds good and looks cool!

    Cons: Face plate does not attach and detach easily

    Crutchfield Customer Review (What's this?)

    First of all, I drive a stripped`down 2002 Ford Ranger. Crank windows. No cruise control. Cloth seats. Paid cash for it in 2009. The factory radio/CD player bit the dust some months ago. Do you know what it's like for a creative person to drive anywhere without MUSIC? Agh. My son, the car guy/music guy/ electronics guy/ fix-it guy recommended Crutchfield. I liked the ease of ordering the right thing for my vehicle. It was a good reasonable price, and arrived promptly and packaged well (that's important to me). My son installed it easily. Nice sound, love all the styling and color changing options (cool), ease of use. Yes, I've hit the wrong button a couple times, but that was in initial use. It's so good to have music again. I'm a classic rock/ blues lover. Highly recommend this company and its products.

    Pros: Ease of ordering and installation. Looks. Style. Fit. Sound. Options.

    Cons: If I'm wearing my sunglasses (it's Texas, so that's 95% of the time), I can't always see the display, but that's b/c my glasses are polarized.

    Sony Upgrade

    Nice balance of features at a high school budget. USB and aux hookup make it easy listen to custom playlists, or go right to the presets. Not sure how much the CD player will get used. Would like a higher quality feel for the volume knob.

    Pros: Multiple media inputs. Good value. Easy install with the install kit into my Jeep.

    Cons: A CD player that will never get used, eliminate the player and lower the cost.

    Outstanding sound from a very moderately priced unit, and a huge upgrade from the factory supplied device.

    Pros: Very easy to instal and the extra instructions relating to my car were very useful. I had it up and running within an hour. Great sound from the I-Pod.

    Cons: It took longer to fully understand the menu and programing than it did to instal

    I love Crutchfield's website and installation instructions, and this Sony head-unit is fine for what it is; I'm sad that I didn't read the fine print under the Details tab under the sub-section titled Disk & USB Playback. This unit says: The USB port enables audio playback & control of MP3/WMA audio files stored on your portable USB Today, I noticed the next more expensive Sony says this: The head unit can play MP3, WMA, AAC, FLAC, and WAV music files stored on compatible USB device. Translation: This Sony will not play music that you copy from your iTunes folders. Caveat Emptor!!

    Old Sony went dead and needed a good cheap replacement and this did the job very well. I like my old Sony and this was the updated version of it. Setup is easy and took about 45mins total.

    Great Graduation Gift

    Crutchfield Customer Review (What's this?)

    This was a gift for one of our youth group students graduating from High school. The price was right and the look was perfect for her tastes. It should make a great first deck for her. The scrolling accent colors we knew would be a hit. The aux input and the USB are just what she needed in addition to having a CD player. Her car still has the pathetic factory speakers so I cannot comment on sound quality. It sounds like mud to me, however she says that it sounds 10 times better than it did before.

    Pros: Looks great, priced right, lots of features and inputs.

    Cons: A little more challenging to operate and set-up than the older SONY units that I have purchased in the past

    Good Reception

    Bought radio as recommended by advisor because it had good reception. Using in a remote cabin with 12V solar system. Good sound and reception.

    Made driving way more fun. My previous stereo had no bass and now it's like I have subs! Would recommend. But the install is unclear and said to remove the antenna and get a new cord but after cutting it off we found you could simply remove it. Cost me 3 extra hours and $20 trying to fix the issue. Otherwise it is awesome



    Sony CDX-G3100

    Crutchfield Customer Review (What's this?)

    I bought this unit to replace an older single DIN Sony that I thought was going south. I wanted a basic receiver that had a front aux input and a CD player, as well. I reused the old mounting kit and harness adapter and it went in with no problem. Until I turned it on. It sounded great for 15 minutes and then the sound just faded out. Turns out that the speaker in the driver's door was damaged and caused the internal amp to go into protection mode. After replacing both front speakers, the system has performed to my expectations. For a bargain priced stereo, it sounds great with the new Sony 6" speakers. My only quibble is with the very small and oddly shaped buttons that my big fingers have trouble getting to easily. The exception is the easy to use volume dial. Overall, a good value for the money.

    Pros: Ease of installation, front aux and USB port, selectable display colors.

    Cons: Except for the volume control knob, buttons for on/off/source and other functions are very small and oddly shaped.

    Works good, doesn't play acc

    Zak from Texas on 6/4/2015

    Crutchfield Customer Review (What's this?)

    Radio is nice and as described but I guess I assumed or didn't think about seeing if it played ACC files from a flash drive (which is iTunes files too I think) which is kinda a bummer. Also can't go back a song when using the flash drive like my older Sony in my e30. Overall a good radio and good upgrade from most stock radios. Has a bunch of LED color options if that's your thing.

    Pros: lots of color settings

    Cons: doesn't play acc or iTunes files off flash drive

    Great Stereo for the price.

    Pros: Easy to use.

    Cons: Display will not dim with dash lights. The display must be manually set to dimmer on or off. It would be nice to have a connection to the dash lights so the display brightness could be controlled with the dash lights rheostat.
