    Product Research

    Features

    Built-In Bluetooth: Thanks to built-in Bluetooth with support for hands-free communication (HFP) and wireless audio streaming (A2DP/AVRCP), you can make hands-free calls and wirelessly stream music from your Bluetooth-enabled smartphone to the Jensen MPR2121 digital media receiver. Before using your Bluetooth enabled device, it must be paired to the Jensen MPR2121 via a SSP (Secure Simple Pairing). You can pair one device at a time with this unit. Once paired, when your Bluetooth device is in close proximity to the Jensen receiver, the auto connection function automatically connects the two units.

    • Hands-Free Communication (HFP): You'll be able to answer incoming calls from the head unit's front-panel or set the unit to answer a call automatically. Incoming phone call information is displayed on the unit's front-panel LCD. You can quickly redial the last number from the head unit, but no other calls can be made from the head unit alone. In order to make a call you must first make the call from your smartphone and it will automatically transfer over to the head unit. Use the integrated front-panel microphone to speak into during your phone conversation, while the other party will be heard through your vehicle's speakers. Your car audio speakers will mute automatically during a call.
    • Wireless Audio Streaming (A2DP/AVRCP): You'll be able to wirelessly stream stored music, music apps, and other audio content from your Bluetooth-enabled smartphone to the Jensen MPR2121 digital media receiver. You'll also be able to control basic playback functions such as Play/Pause and Previous/Next Track. Advanced music navigation and song/artist/album information must still be done from your smartphone device. This unit does not display song/artist/album information from a Bluetooth device.

    Note: The Jensen MPR2121 does not come with an external microphone and does not support connection of an optional external mic.

    Voice & App Control: The Jensen MPR2121 also supports Push-To-Talk Voice Assistance and App control via Bluetooth for compatible Apple iPhones and Android smartphones.

    • Push-To-Talk Voice Assistant: When connected via Bluetooth to an iPhone with Siri or Android smartphone with Google Assistant or Bixby, you can access the mobile device's digital voice assistant through the Jensen receiver by pressing the "Push-to-Talk" button on the front-panel. You'll speak your command into the head unit's front-panel microphone and the digital voice assistant will be heard through your vehicle's speakers (music playback will be attenuated). Compatible digital voice assistant functions include hands-free calling, music search, setting reminders, text-messaging, audible navigation, and more. You'll be able to ask your digital voice assistant 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 compatible smartphone. The head unit's audio is attenuated while the digital voice assistant provides voice prompts.
    • J-Link P2 Smart App: The J-Link P2 app (for Apple iOS 9.1+ and Android OS 5.0-13.0) connects to the Jensen receiver via Bluetooth and allows you to control select functions of the receiver from your compatible Apple iOS or Android OS smartphone device. Supported control functions include Power, Source, Volume, Tuning, Playback, Audio Settings, and more.

    Note: The MPR2121 does not come with a wireless remote control and does not support steering wheel control.

    USB Port: The front-panel USB (type-A) port allows you to connect a USB MSC (Mass Storage Class) device, such as a USB thumbdrive. The unit supports playback of MP3 and FLAC music files, basic playback control, song/artist/album information display, and charging via USB.

    • Control: You'll be able to control playback functions such as Folder/File Access, Play/Pause, Previous/Next Track, Repeat (All/One/Folder), Radom (All), and Intro (10 seconds).
    • Display: The receiver will display the song/artist/album information from your MP3 music files loaded onto a USB thumbdrive.
    • Charging: The USB port is rated at 5V/1A and can be used to charge your smartphone device when the vehicle and/or radio is powered on..

    Note: The USB port does not support playback from an Apple iOS or Android OS device. The USB port does not support USB hubs or card-readers.

    Aux Input: The front-panel Aux input consists of a female 3.5mm minijack that allows you to connect an external audio device that features an analog output or headphone jack.

    AM/FM Tuner: The Jensen MPR2121 digital media receiver offers a built-in AM/FM tuner with manual, seek, and preset tuning. You can store up to a total of 30 radio station presets (18 FM / 12 AM). Preset stations can be stored manually or automatically. You can select between US and European tuning.

    CTA-2006 Compliant Amplifier: The power specifications for the Jensen MPR2121 are compliant with the CTA-2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Technology Association (CTA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers.

    • CTA-2006 Specs: 16 watts x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
    • Maximum Power Output: 50 watts x 4 channels (200 watts total)

    2V/6Ch Preouts: The Jensen MPR2121 is equipped with three pair of 2-volt preouts for the front, rear, and sub channels. The front and rear channels are fading, while the subwoofer output is non-fading.The head unit does not offer independent subwoofer control (there is no adjustable sub level and no low-pass crossover).

    Audio Settings: The Jensen digital media receiver offers 5 Preset EQ Curves - Classic, Pop, Rock, Flat, and User. The User mode allows you to manually adjust the head unit's Bass & Treble from -7 to +7dB. Activating the Loudness feature will enhance the bass and treble frequencies when listening to music at low volumes. You can also set the head unit to turn on at a specific volume each time you turn the unit off and on.

    Variable Color Illumination: The head unit's large 12 character LCD provides you with a comfortable viewing experience, featuring a Clock display and support of song/artist/album information from a connected USB MSC device. You can choose between 32,000 color combinations for the LCD and button illumination (the LCD and button illumination are not discrete and will be the same color). The LCD screen also offers dimmer and brightness adjustments.

    Key Beep: When this function is enabled, every button press will output a beep tone.

    Have a factory radio in 2012 Jeep Liberty. Will I need the installation kit with this radio?
    alex  Nov 09, 2024
    1 answer
    A
    Greetings Alex. Thank you for your question. Aftermarket stereos are universal, and in most all cases would need installation gear to install them. If your 2012 Liberty still has the factory radio, you will need an install package as well.
    thomas  Nov 09, 2024 (Staff)
    Q
    I purchased this radio along with the mounting kit and harness for my sons 94 F150. Everything works fine but when we shut the truck off and start it back up the radio has no memory. Which wires need to be spliced together for the memory to work?
    amy  Jul 30, 2024
    1 answer
    A
    Greetings Mike, and thank you for your purchase. The yellow wires on the Jensen harness and the yellow wire on your Metra wire adapter are the constant memory wires. If they are connected already, you could try running the Jensen yellow wire straight to the battery and see if it holds memory. If not, we need to send you a new stereo.

    In most cases, a filler pocket is included with a vehicle-specific dash kit to fill the gap left over with a single-DIN radio. Our advisors are happy to help with selecting the correct installation parts via online chat or phone at 1-800-324-9695.

    Q
    Do I need a wiring harness or will the cable that's already in the dash plug right into the new stereo?
    riley  Oct 18, 2023
    1 answer
    A
    Greetings Riley. Thank you for your question. If your vehicle has the factory radio still, you will need an adapter to install an aftermarket stereo. If you have an aftermarket stereo and are replacing it with this Jensen, you already have an adapter that you could re-use to install this Jensen.

    Q
    What wiring harness will I need to install this in a 2001 Nissan Pathfinder SE that has a Pioneer DEH-5100UB in it currently? https://
    www.crutchfield.com/S-cpO7oDCFPxA/p_130P5100UB/Pioneer-DEH-P5100UB.html the OEM steering volume/mode control ability will be awesome. I'm confused about the factory amplifier note that pops when I review this item.

    A
    This Jensen MPR2121 Digital media does not support steering wheel controls sadly, Sarwat. We also need to know the exact trim level of your Pathfinder to advise on the exact harness. If you have the Bose package but no navigation originally in your 2001 Pathfinder SE the link below would be the harness and package to use, we can even wire it with our ReadyHarness service to make the radio swap easy! https://www.crutchfield.com/I-rXYEc222/cart/EmailCart.aspx?emKey=3166624

    A
    If you only need radio Toni, the Jensen MPR2121 digital media receiver offers a built-in AM/FM tuner with manual, seek, and preset tuning. This is one of our most affordable radios and you will get some bonus features like the Bluetooth capability as well! This radio fits in your 4Runner and would be a great choice for radio use only.

    Q
    I have a 2011 Jeep Patriot , this wouldn't be a snug fit in my jeep but my question is about the casing I guess , what would I do so there isn't a big gaping hole under my radio ? Or does it come with a casing ?
    jasmine  Nov 06, 2022
    1 answer
    A
    When you get your radio from us Jasmine, we really want to make sure you also get everything you need paired with the radio! When you punch in your 2011 Jeep Patriot into our website, it will show you the available install packages for your specific ride. You'll want to make sure you input your ride's trim specifics too (any sort of premium sound originally or navigation). It looks like with this sweet Jensen MPR2121 you will use this Metra dash kit in the link below, this takes up that space and makes the radio install look clean! https://www.crutchfield.com/p_120996511/Metra-99-6511-Dash-Kit-Black.html

    mitchell  Oct 18, 2022

    You press and hold the volume knob momentarily and then rotate between the audio functions and press to activate. There is a User Mode which will allow you to manually adjust Bass and Treble from -7 to +7dB.

    Does this radio allow you to control treble, mid, and bass individually?
    eric  Aug 29, 2022
    1 answer
    A
    It does not have a midrange EQ band to adjust; it only has bass and treble. We offer other receivers that do have the midrange control as well. I recommend contacting an advisor by calling 1-800-324-9695 to get a personal recommendation
