And built-in Bluetooth® connectivity will make your driving safer and more entertaining. Once you experience hands-free calling, you'll never go back.

Ideal for Apple or Android

If you store your music on an Android device, the KMM-BT312U is the answer to your prayers. Android Open Accessory protocol (AOA) lets you connect your phone either to the front USB port or through Bluetooth, then control all the music you've stored there. You'll be able to run the apps you like and take advantage of a variety of search and playback features.

Got an iPod® or iPhone®? You can plug your player into the KMM-BT312U's front-panel USB input to access your playlists. Dedicated "search" and "return" buttons, plus handy tools like AppMode, Alphabet, Percentage Skip, and Related Search, help you find your music fast. With a compatible iPhone, you can also enjoy the convenience of full Siri® Eyes Free control.

You don't have to rely on your phone for entertainment, however. You can liven up your travels by plugging in a thumb drive or jacking another device into the front-panel aux input. The KMM-BT312U can play MP3, WMA, AAC, WAV, and FLAC music files, so you'll be able to enjoy your entire music library. The variable-color 1.5-line LCD display makes it easy to see song titles and channel information with just a glance.

The centerpiece of your system

In addition to being the perfect host for all your digital devices, the KMM-BT312U gives you lots of options for expanding. You can add a satellite radio tuner (subscription also required) to enjoy SiriusXM's remarkably varied range of music, entertainment, news, and sports programming wherever your travels take you. If you're planning to build a really rockin' system, the KMM-BT312U makes a great starting point. This high-performance receiver offers three sets of preamp outputs, so you'll be in good shape when you add amplifiers and subwoofers to your system.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.

    Built-in Bluetooth

    Bluetooth Technology: The Kenwood KMM-BT312U is equipped with built-in Bluetooth (ver. 2.1+EDR/3.0) 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 compatible and be able to interpret certain profiles. This unit is compatible with the following Bluetooth Profiles:

    • Hands-Free Communication: HFP 1.5 (Hands Free Profile), OPP 1.1 (Object Push Profile), PBAB 1.0 (Phone Book Access Profile).
    • Audio Streaming: A2DP 1.2 (Advanced Audio Distribution Profile), AVRCP 1.3 (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-BT312U. Visit Kenwood's Support Site for a complete list of compatible Bluetooth enabled phones.

    Secure Simple Pairing (SSP) + Auto Pairing (for iPhone): With Secure Simple Pairing (SSP), you can easily pair a Bluetooth enabled phone to the Kenwood KMM-BT312U without having to enter pin codes or go through complicated settings. When a paired Bluetooth device is in close proximity to the receiver, the auto connection function automatically pairs the two units. You can pair up to five Bluetooth-enabled devices to the Kenwood head unit, but only one can be used at a time. 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.

    Bluetooth Hands-Free Communication: The head unit supports Bluetooth hands-free communication for your Bluetooth enabled mobile phone. The controls of the KMM-BT312U 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-BT312U 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.
    • Dialing a Number: Using the KMM-BT312U, you can dial a phone number in one of the following ways:
      • Entering a Phone Number: Allows you to directly dial a phone number up to 32 digits from the head unit's control knob or remote control.
      • Speed (Preset) Dialing: 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.
      • Phone Book: You can dial by using the downloaded phone book. You can download phone book data from your cell phone to the KMM-BT312U. Up to 600 numbers can be stored for each registered cell phone. Each number can be up to 32 digits long and each name can be up to 50 characters long.  Stored phone numbers can be categorized by General, Home, Office, Mobile, or Other. You can search each category of the phone book in alphabetical order.
      • Call History: The Call History is a list of calls that have originated from and were received by this unit that you can dial. You can select Outgoing, Incoming, or Missed calls.
      • Voice Dialing: If your mobile phone supports voice recognition, then you can dial out by voice command. Simply speak into the included microphone.

    Note: 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 and noise 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. The external microphone measures 0.525" (diameter) x 1.505" (depth).

    Wireless Audio Streaming (w/ AAC): The Kenwood KMM-BT312U supports wireless audio playback (AD2P) and control (AVRCP) of a Bluetooth-enabled smartphone or audio player, plus song/artist information display and support for AAC music streaming.

    • Stored Music & Music Apps: 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-BT312U for playback.
    • SBC + AAC Codecs: In addition to support for the standard SBC Bluetooth audio codec, the KMM-BT312U offers support of AAC.  By supporting AAC, the KMM-BT312U offers better audio performance of the music streamed from your Apple iPod, iPhone, or iPad.
    • Basic Playback Control: You can use the front-panel controls of the KMM-BT312U to operate basic playback functions of your Bluetooth device's stored music & music apps; such as Play/Pause, Skip Next/Previous, Fast Forward/Rewind and Random/Repeat (not compatible with all apps). Advanced music control of your stored music and music apps will still need be done via your Bluetooth-enabled smartphone.
    • Song/Artist Information: The head unit will also display your stored music and music app's song information; such as Artist name and Song/Album title (not compatible with all apps).
    Note: 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.

    Siri Eyes Free Control: When paired and connected to an iPhone with Siri via Bluetooth, the Kenwood KMM-BT312U 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-BT312U 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-BT312U; visual data will still need to be viewed from your iPhone device).
    iPhone & Android Integration

You can choose between two operating modes.

    • Head Unit Mode + Song/Artist Info: From the head unit's front-panel controls you can search for stored music by Playlist, Artist, Album, Song, Podcast, Genre, and Composer. The contents of a Playlist or Category can be searched alphabetically (A-Z) or numerically (0-9). The KMM-BT312U also supports Repeat (file/all) and Random (album/all) playback functions of stored music on your iPod/iPhone. 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. During Head Unit Mode, the KMM-BT312U will display your iPod/iPhone's music file information such as Track number, Elapsed playing time, Artist name, Song title, and Album title. Newer iPod/iPhones with iOS 6.0+ allow you to continue to access your Apple device's touchscreen in this mode in order to access other applications; older iPod/iPhone devices will be locked during connection.
    • iPod/iPhone Mode: The iPod/iPhone Mode lets you control your older iPod/iPhone (iOS 5.1.1 and earlier) from its clickwheel or touchscreen. You'll still have access to basic playback controls (like Play/Pause & Previous/Next Track) from the head unit, but advanced navigation functions will be locked. No song/artist information is displayed in this mode. The unit will simply display "App & iPod Mode".

    MOSFET Amplifier: The Kenwood KMM-BT312U is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit. The power output specs for the KMM-BT312U are as follows:

    • Full Bandwidth Power: 22 watts RMS x 4 channels (at 4 ohms, 20-20kHz, 1% THD)
    • Maximum Output Power: 50 watts x 4 channels

    • Low Pass Filter: The receiver features a built-in Low Pass Filter control for the preamp-output, when the output is set to Subwoofer. You can select from 85 Hz, 120 Hz, 160 Hz, or off.
    • Subwoofer Phase: You can adjust the phase of the subwoofer output between 180-degrees (Reverse) or 0-degrees (Normal).
    • Subwoofer Level: Once the Subwoofer preamp output is activated, you can independently control the subwoofer preamp output level (-15 to +15) from the digital media receiver.

    Front & Rear High-Pass Filter: The KMM-BT312U features a High-Pass Crossover for the front & rear channels when your front & rear speakers are connected by the unit's speaker-outputs or preamp-outputs. You can adjust the high-pass crossover from "Through", 100, 120, or 150 Hz. The "Through" selection is a full-range setting.

    Speaker Settings: The Speaker Setting function tailors the head unit's audio settings according to the type of speakers in your vehicle. You may select a Speaker Setting of 'SP-Off' (flat/off), 'SP-OEM' (for OEM factory speaker systems), 'SP-6x9/6' (for systems with 6" and 6"x9" speakers), or 'SP-5/4' (for systems with 4" and 5" speakers).

The integrated equalizer offers 8 preset sound modes (Rock, Pops, Easy, Top 40, Jazz, Natural, Drive EQ, or User) suitable for the music genre of your choice. The Drive EQ mode is an EQ preset that helps reduce road noise. The User mode allows you to manually adjust the head unit's 3-band parametric EQ (Frequency, Level, and Q-Factor).

    EQ Pro
    Frequency Level Q
    Bass 60, 80, 100, 200 Hz -8 to +8 1.0, 1.25, 1.5, 2.0
    Midrange 0.5, 1.0, 1.5, 2.5 kHz -8 to +8 0.75, 1.0, 1.25

    Sound Enhancements: The head unit provides further sound enhancements for your car audio system.

    • Bass Boost: The Kenwood digital media receiver features a Bass Boost control that can be set to the following levels (1-3 or off).
    • Loudness: This function enhances low and high frequencies to make the sound clearer lower volumes. There are 3 levels (1-2 or Off).
    • Sound Reconstruction: When MP3 or WMA files encoded at a low bit rate (less than 96 kbps, 44.1k, 48kHz) are played, the Sound Reconstruction function restores their high frequencies so the sound quality is closer to files encoded at a high bit rate. The processing is optimized for the compression format and the bit rate used. When Sound Reconstruction is Off, the unit plays the original sound stored in the audio file.
    • Volume Offset: The level of each source may be independently adjusted to prevent radical leaps in output volume when switching from one source to another. The available settings range from -8 to 0 (-8 to +8 for Aux source).

    No, not this unit. We have marine units that are very similar, although none are waterproof the marine units are water resistant. They have special coatings and covers for the front panel inputs.
