Music, music everywhere

Kenwood steps up your app experience in the car by giving you control of your smartphone from the KMM-BT225U with a wired connection. Navigate your favorite playlists and explore new music on Spotify and Pandora.

If you keep music saved on your phone, a music player, or a thumb drive, accessing it is as simple as plugging into the USB input. The KMM-BT225U can play MP3, WMA, AAC, WAV, and even high-res FLAC music files, so you can access your entire music library. With a wired connection to your iPhone®, you'll be able to take advantage of a variety of search and playback features from the KMM-BT225U. And hey, Android users... you can connect your phone either to the front USB port or through Bluetooth and then control all the music you've stored there.

Other smartphone perks

For the times when you're sharing the ride, the KMM-BT225U enables you to 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. You can also control this stereo directly from your iPhone® or Android™ phone using Kenwood's free Remote app.

Craft the sound you're looking for

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

    Built-in Bluetooth

    Bluetooth 3.0: The Kenwood KMM-BT225U is equipped with built-in Bluetooth (ver. 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 and be able to interpret certain profiles. This unit is compatible with the following Bluetooth Profiles:

    • Hands-Free Communication: HFP 1.6 (Hands Free Profile), PBAB 1.0 (Phone Book Access Profile).
    • Audio Streaming: A2DP 1.2 (Advanced Audio Distribution Profile), AVRCP 1.5 (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-BT225U. 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-BT225U without having to enter pin codes or go through complicated settings. You can even pair your Apple iPhone (iOS 5+) or Android smartphone (running Kenwood Music Play App) by simply connecting it to the Kenwood head unit via USB and following a single prompt on the head unit's display.

    • 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.
    Note: 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.

    Bluetooth Hands-Free Communication: The head unit supports Bluetooth hands-free communication for your Bluetooth enabled mobile phone. The controls of the KMM-BT225U 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-BT225U 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-BT225U, you can dial a 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.
      • Phone Book: You can download phone book data from your mobile phone to the KMM-BT225U. You can then dial a contact within the phonebook from the head unit's front-panel controls. Contacts are categorized as Home, Office, Mobile, Other, or General.
      • 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.
    • 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.

    Wireless Audio Streaming: The Kenwood KMM-BT225U 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-BT225U for playback.

    • SBC + AAC Codecs: In addition to support for the standard SBC Bluetooth audio codec, the KMM-BT225U offers support of AAC.  By supporting AAC, the KMM-BT225U 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-BT225U 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).
    • 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-BT225U 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-BT225U 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-BT225U; visual data will still need to be viewed from your iPhone device).

    Android & iPhone Integration

    Android Open Accessory 2.0 (AOA 2.0) Connectivity: The Kenwood KMM-BT225U's front-panel USB port lets you connect select Android (OS 4.1-7.1.2) smartphones that support AOA 2.0 for music playback. Kenwood does not guarantee operation with all Android devices, regardless of operating system. There are two Android AOA 2.0 modes to choose from based on what content you want to listen to and how you want to control it.
    • Hand Mode: The Kenwood KMM-BT225U supports Android Open Accessory 2.0 (AOA 2.0), which lets  you connect your Android (OS 4.1-7.1.2)  smartphone to the KMM-BT225U's front-panel USB port and listen to stored music and music apps from your Android device through the Kenwood head unit. You'll be able to control basic playback functions such as Play/Pause and Previous/Next Track. Other advanced music navigation will still be done from your Android smartphone's touchscreen. In this mode, the head unit will not display song/artist information; only "Hand Mode" will show up on display. You'll continue to view song/artist information from the Android device's touchscreen. You'll also still be able to access other functions and applications from your Android smartphone's touchscreen, while listening to music through the head unit. If you make a call or answer a call from your smartphone while listening to music in this mode, the music will pause until you are finished with the call and then start back up again.
    • Browse Mode (via Kenwood Music Play App): Downloading the Kenwood Music Play app onto your Android (OS 4.1-7.1.2) smartphone with AOA 2.0 support not only allows you to listen to stored music from your Android device through the Kenwood digital media receiver connected via USB, but it also lets you browse your Android smartphone's music library from the head unit's front-panel controls. You can browse your store music library by Playlist, Artist, Song, Album, or Genre. The contents of a Playlist or Category can be searched alphabetically or numerically; you can even skip through the stored music files in specific increments (0.5/1/5/10%). You can also control Play/Pause and Previous/Next track from the head unit. In addition, the head unit will display song/artist information. You can exit the Kenwood Music Play app to access other functions and applications of your Android smartphone, while your stored music library is still playing through your head unit. If you make a call or answer a call from your smartphone while listening to music in this mode, the music will pause until you are finished with the call and then start back up again.
    Note: Some Android devices may not support Android Open Accessory (AOA) 2.0. Kenwood does not guarantee operation with all Android devices.

    iPhone Direct Connection: The Kenwood KMM-BT225U's front-panel USB port can be used to connect your Lightning Apple device or 30-pin iPhone 4S to the head unit. The USB connection allows for playback of stored music and music apps on your iPod or iPhone through Kenwood receiver. If you have a newer iPod/iPhone with the Lightning-connector, you can use Kenwood's Lightning connector-to-USB cable (113KCIP103 sold separately) or the Lightning-to-USB cable that came with your Apple device to connect your iPod/iPhone to the KMM-BT225U. If you have an iPhone 4S with a 30-pin dock connector, you can use the dock connector-to-USB cable that comes with your Apple device or a 3rd party "Made for iPod/iPhone" certified dock-to-USB cable (sold separately) to connect your iPhone 4S to the KMM-BT225U.

    • Head Unit Control: 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 or numerically; you can even skip through the stored music files in specific increments (0.5/1/5/10%). The KMM-BT225U 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. You can also choose to control your compatible Apple iPhone or touch from its own touchscreen, instead of the head unit.
    • Song/Artist Info Display: The KMM-BT225U will display your iPod/iPhone's music file information such as Track number, Elapsed playing time, Artist name, Song title, and Album title.

    Smartphone Charging: The head unit's USB connection provides 1.5A of current to power and charge your connected Apple iPod/iPhone or Android smartphone when your vehicle's ignition switch is set to the 'ACC' or 'On' position (if your iPod/iPhone has no initial battery charge, then the unit will not recognize it).

    Audio Section

    24 Bit D/A Converter: The Kenwood KMM-BT225U utilizes a 24-bit digital to analog converter for superior sound quality.

    MOSFET Amplifier: The Kenwood KMM-BT225U 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-BT225U 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

    2Ch/2.5V Pre-Outs + Sub Control: The KMM-BT225U is equipped with one pair of 2.5V pre-outs (Rear/SW). You can set the Rear/SW preamp outputs for connecting a pair of full-range rear speakers (through an external amplifier) or for connecting a subwoofer (through an external amplifier). When set for rear speakers, the rear outputs operate with the unit's fader control. When set for subwoofer, the outputs are non-fading. Once the Subwoofer preamp output is activated, you can independently control the subwoofer preamp output level (-15 to +15) from the digital media receiver.

    Vehicle Settings: In order to optimize the sound quality in your vehicle, you can indentify the type of vehicle you have, select speaker sizes & locations, as well as configure listening distances.

    • Car Type: Select your car type to automatically set the delay time of each speaker for timing adjustment of sound output of each channel to have the highest surround effect. Choose from Compact, Full Size Car, Wagon, Mini Van, SUV, or Off
    • Speaker Size: You can select which size speakers are in your vehicle - Tweeter (Small, Medium, Large, or None), Front & Rear (3.5", 4", 4.75", 5", 6.5", 6.75", 7", 4x6", 5x7", 6x8", 6x9", 7x10" or None), and Sub (6.5", 8", 10", 12", 15" or Over, None).
    • Rear Speaker Location: You can indicate the location of your vehicle's Rear speakers. Choose from Door, Rear Deck, 2nd Row, or 3rd Row.
    • DTA (Digital Time Alignment): For a better sound-stage you can select your optimal listening position. You can choose from All, Front Left, Front Right or Front. You can also select to manually fine tune the sound stage, using Digital Time Alignment (DTA) by selecting the distance (0-20') for each individual speaker in the vehicle compared to your listening position.

    High Pass & Low Pass Crossovers: You are able to select independent high pass crossovers for your tweeters, front speakers, and rear speakers; as well as a low pass crossover for the head unit's sub output.

    • Tweeter: Set high pass filter (HPF) for tweeters.
      • Frequency: 1kHz, 1.6kHz, 2.5kHz, 4kHz, 5kHz, 6.3kHz, 8kHz, 10kHz, 12.5kHz
      • Gain: -8 to 0 dB
    • Front & Rear: Independently set high pass filter (HPF) for front & rear speakers.
      • Frequency: 30Hz, 40Hz, 50Hz, 60Hz, 70Hz, 80Hz, 90Hz, 100Hz, 120Hz, 150Hz, 180Hz, 220Hz, 250Hz, Through (Full-Range)
      • Slope: -6dB, -12dB, -18dB, -24dB
      • Gain: -8 to 0 dB
    • Sub: Set low pass filter (LPF) for the sub output.
      • Frequency: 30Hz, 40Hz, 50Hz, 60Hz, 70Hz, 80Hz, 90Hz, 100Hz, 120Hz, 150Hz, 180Hz, 220Hz, 250Hz, Through (Full-Range)
      • Slope: -6dB, -12dB, -18dB, -24dB
      • Phase: Reverse (180°), Normal (0°)
      • Gain: -8 to 0 dB

    Equalizer: The Kenwood KMM-BT225U offers 8 EQ Presets for easy adjustment, a 13-band EQ for customized tuning, a Drive EQ mode to overcome road noise, and a Stage EQ for better imaging. Separate EQ settings and EQ presets can be stored for each source or you can apply one EQ preset or curve to all sources.

    • Preset EQ: 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.
    • 13-Band EQ: The User mode allows you to manually adjust the head unit's 13-band EQ (62.5Hz, 100Hz, 160Hz, 250Hz, 400Hz, 630Hz, 1kHz, 1.6kHz, 2.5kHz, 4kHz, 6.3kHz, 10kHz, & 16kHz). Each frequency's gain level can be adjusted from -9dB to +9 dB, while the Q-factor can be adjusted to 1.35, 1.5, or 2.0
    • Drive EQ: The Drive EQ mode helps you hear your music over road noise. It boosts certain frequency ranges that become hard to hear due to road noise.
    • Stage EQ: Stage EQ virtually lifts the sound up to ear-level for better imaging inside your vehicle.

    Audio Settings: The Kenwood KMM-BT225U offers a variety of audio settings to further enhance your music listening experience.

    • Sound Reconstruction: When MP3, WMA, AAC 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.
    • Space Enhancer & Sound Realizer: The Spacer Enhancer widens the soundstage inside your vehicle, while the Sound Realizer makes your music sound more realistic.
    • Loudness, Bass Boost & Bass Extension: The Loudness feature boosts low and high frequencies to produce a well-balanced sound at a low volume level. The unit's Bass Boost enhances low bass frequencies at any volume level. There is also a Bass Extension feature which further enhances the unit's bass output at extremely low frequencies.
    • 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 -15 to +6.

    Key Beep: The in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

    Remote Control

    Remote App (for Apple iOS): The Kenwood Remote App (for Apple iOS 8.0+) operates the Kenwood receiver like a wireless remote control from your USB or Bluetooth connected Apple iOS device. The Kenwood Remote App provides traditional touchscreen control, as well as directional and freeform gesture control from your compatible mobile device.

    • Source Selection: The Kenwood Remote App provides list of the receiver's built-in sources and connected sources (CD, Aux, AM/FM, USB, Bluetooth); so you can select which source you want to listen to from the app on your mobile device. 
    • Playback Control: The application lets you control CD, USB, and Bluetooth audio playback. You have control of Play/Pause, Previous/Next Track, and Repeat/Random. From the app you can also select AM/FM bands, select preset stations, and seek AM/FM stations.
    • Display Information: The app also displays source information such as station number, track number & playback time, as well as song/artist/album information (when applicable)
    • Audio Settings: From the application on your mobile device, you can adjust the receiver's volume up or down. In addition, audio settings such as EQ, Crossover, DTA, and other audio adjustments can be easily set using the Kenwood Remote application.
    Notes:
    • When using the Kenwood Remote App with your compatible Apple iOS device, the application and device must be connected to the receiver via Bluetooth (not USB) for playback of Bluetooth audio. For playback of a USB-direct connection from an Apple iOS device, the device and application must be connected to the head unit via USB (not Bluetooth).
    • The Remote App is no longer compatible with any model Android OS device (as of 1/1/2019).

    Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input wire (blue/yellow) within the included wiring harness 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).

    Optional IR Remote: The KMM-BT225U is compatible with Kenwood's IR remote control (RC-406, sold separately) for wireless operation of the receiver.

    Display Features

    Detachable Face: The Kenwood KMM-BT225U features a detachable faceplate to deter theft. There is no protective face case included. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit. A face-fixing screw is supplied for making the face non-detachable, if desired.

    Single-Line Display: The KMM-BT225U is equipped with a single-line display with white text and a black background. The button illumination is blue You cannot adjust the color of the display or button illumination. You can select between English or Spanish text.

    A
    Generally I prefer Pioneer head units, but I will be installing this in my mother's car because the controls and button layout seem more user friendly and less technical/ cluttered than the pioneer option at this price point. Replacing the factory stereo to give her hands free calling ( doesn't do well with ear pieces), and a front aux port to run a cassette player( yes, you read that right) until I can digitize her music [ Justin  Dec 26, 2018 ]
