Plenty of sources
With a wired connection to your compatible phone, the KMM-BT228U lets you navigate your favorite playlists and explore new music on Spotify, Pandora, and Apple Music.

For the family ride, Kenwood lets you pair two Bluetooth-equipped phones and quickly switch between them for hands-free calling. And when you're streaming audio, Kenwood's Music Mix feature lets you pair five phones so everybody can pick their tunes for the ultimate road trip party.
Kenwood sound reconstruction restores the depth that's often missing from compressed music files, and digital time alignment ensures that all that sound reaches your ears at the same time. A 13-band EQ lets you get the sound you like, and with their Remote app, you can tune it from your phone.

Bluetooth 4.2: The Kenwood KMM-BT228U is equipped with built-in Bluetooth (ver. 4.2) allowing you to make and receive phone calls wirelessly through the receiver; as well as stream music wirelessly from your smartphone to the head unit. In order to use Bluetooth wireless technology, your phone must also be Bluetooth and be able to interpret certain profiles. This unit is compatible with the following Bluetooth Profiles:
- Hands-Free Communication: HFP 1.7 (Hands Free Profile), PBAB 1.0 (Phone Book Access Profile).
- Audio Streaming: A2DP 1.2 (Advanced Audio Distribution Profile), AVRCP 1.6 (Audio/Video Remote Control Profile).
Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Kenwood KMM-BT228U. Visit Kenwood's Support Site for a complete list of compatible Bluetooth enabled phones.
SSP & USB Pairing: With Secure Simple Pairing (SSP), you can easily pair a Bluetooth enabled phone to the Kenwood KMM-BT228U without having to enter pin codes or go through complicated settings. You can even pair your Apple iPhone (iOS 5+) by simply connecting it to the Kenwood head unit via USB and following a single prompt on the head unit's display. You can pair up to five Bluetooth-enabled devices to the Kenwood head unit. When an already paired Bluetooth device is in close proximity to the receiver, the auto connection function automatically pairs the two units.
- Dual Phone Connection: Thanks to the Dual Phone Connection feature, two Bluetooth-enabled phones can remain connected to the Kenwood receiver. This means you can an answer an incoming call from either phone from the head unit. Also, both of your phone's contact lists are downloaded to the receiver. To make a call from one of the phones using the Kenwood receiver, you simply have to select Phone 1 or Phone 2 on the head unit's front-panel.
- Music Mix: The new Music Mix feature allows five Bluetooth audio source devices to be connected to the Kenwood receiver at one time, so you can switch between Bluetooth playback sources a lot easier and quicker. While "BT Audio" source is selected on the head unit, you can simply press the music playback button on your connected Bluetooth source devices to switch between devices and begin music playback. However, you cannot stream audio from two different Bluetooth audio source devices at the same time or combine music libraries or playlists from two different connected devices.
Bluetooth Hands-Free Communication: The head unit supports Bluetooth hands-free communication for your Bluetooth enabled mobile phone. The controls of the KMM-BT228U can be used to dial a number, answer an in-coming call, or end a call. The unit also includes an external microphone (featuring adjustable gain), so you can carry on your side of the conversation while listening to the caller through your vehicles speakers. During a conversation, you can switch between the Private Mode (talking directly on your cell phone) and the Hands Free Mode.
- Answering a Call: When a call comes in, a ring-tone will be heard through your vehicle's speaker and the caller's name or phone number will be displayed. You can answer the call from the head unit's front-panel controls, or setup the head unit to automatically answer the incoming call immediately or after 1-30 seconds. The KMM-BT228U also supports the Call Waiting function, so you can answer another incoming call while suspending the current call you are on. Your compatible cell-phone must also support this feature.

phone number in one of the following ways:
- Enter Phone #: Allows you to directly dial a phone number up to 32 digits from the head unit's control knob or remote control.
- Preset Dial: Allows you to register up to 6 phone numbers for quick dialing. The preset numbers can be accessed from the head unit's front-panel controls.

- Voice Dialing: If your mobile phone supports voice recognition, then you can dial out by voice command. Simply speak into the included microphone.
Wireless Audio Streaming: The Kenwood KMM-BT228U supports wireless audio playback (AD2P) and control (AVRCP) of a Bluetooth-enabled smartphone or audio player. You are able to stream your stored music library on your Bluetooth-enabled smartphone, as well as music apps downloaded on your smartphone to the Kenwood KMM-BT228U for playback. When an incoming call or outgoing call is in progress from your Bluetooth enabled mobile phone, audio streaming will be paused so you can take your call. Once the call is finished, your streaming music will resume.
- SBC + AAC Codecs: In addition to support for the standard SBC Bluetooth audio codec, the KMM-BT228U offers support of AAC. By supporting AAC, the KMM-BT228U offers better audio performance of the music streamed from your Apple iPod, iPhone, or iPad.
- Advanced Music Browsing: In addition to basic playback functions (Play/Pause, FF/RW, Skip, Random/Repeat), the KMM-BT228U lets you browse your stored music by Playlist, Artist, Album, Song, etc. Advanced music browsing is supported by Android 4.0+ smartphones and Apple iPhones 5.0+ (specific advanced functions vary by phone).

Siri Eyes Free Control: When paired and connected to an iPhone with Siri via Bluetooth, the Kenwood KMM-BT228U has the ability to access Siri through its front-panel controls and external microphone. Simply press-and-hold down on the head unit's Answer Button to engage Siri and use the included microphone to communicate with Siri. Siri's voice will heard through your vehicle's speakers. All Siri functions including hands-free calling, music search, setting reminders, text-messaging, audible navigation, and more can be done through the KMM-BT228U and its microphone. You even can ask Siri to get directions to a destination and the turn-by-turn instructions will heard through your vehicle's speakers, while the on-screen map still displays on your iPhone with Siri. The head unit's audio is attenuated while Siri provides audible directions.
Note: The head unit's display will only indicate hands-free calling and Bluetooth audio information (all other functions of Siri are only audible through the Kenwood KMM-BT228U; visual data will still need to be viewed from your iPhone device).
External Mic: The external wired microphone offers improved audio quality versus an integrated microphone, so you can be heard easier over noisy traffic and road noise. You can adjust the volume level, noise cancellation, and echo cancellation of the microphone without affecting the other sources. The external microphone features an attached 10' cable terminated by a right-angle 3.5mm connector which plugs into the mic input on the rear-panel of the head unit. The microphone offers an integrated mounting bracket which can be clipped to your vehicle's sun-visor or taped to your dash.

In addition, you'll be able to control basic playback functions (such as Play/Pause, Previous/Next Track) from stored music and select music apps streamed to your iPhone. You can also choose to control your compatible Apple iPhone or touch from its own touchscreen, instead of the head unit.
