Grom Audio's simple and low cost aux-input kit will allow a direct sound connection to ensure excellent sound quality.

Aux 3.5mm car audio input: Just plug the device into the extension port or CD changer port of your stereo, connect it to your favourite MP3 player, iPod, iPhone, or Android device and hear the CD quality music right away!

Data Cable:

Each Grom Audio kit comes with one vehicle specific cable (data cable) for connection to the car. A BMW has a choice of two:

  • Connection into the back of the radio (except on navigation models) requires the BMWS cable, please click here for installation instructions.
  • CD changer connection usually located in the boot requires the BMWT cable, please see the video clip.


Kit Contents:

  • Car stereo adapter in plastic enclosure
  • 1.5m cable with 3.5mm male jack
  • Vehicle specific cable to connect to CD changer port BMWT
  • User manual  

Optional accessories and upgrades - sold separately:

  • Flush Mount 3.5mm female auxiliary cable (CFM35)
  • High power USB socket car charger (UGC257)

Please note:  With a simple aux-input into the car stereo no control over the music playing is available via the radio/steering wheel buttons.  Please see our other kits that will allow this functionality.

*** Important for 2005+ BMW X3; 2006+ BMW Z4:

BMW X3 (E83) production date 09/2005 and up with DSP without navigation, CD changer and iPod connection
BMW Z4 (E85) production date 02/2006 and up with DSP without navigation, CD changer and iPod connection
BMW Z4 (E86) coupe production date 05/2006 and up with DSP without navigation, CD changer and iPod connection

These vehicles above do not require GROM DSP adapter (use analog DSP) and can be installed at stereo or trunk, but the audio part will not work until the stereo is programmed (retrofitted) to accept CD Changer (BMW calls it “vehicle order”). Please contact your local BMW dealer and ask them to retrofit the stereo to accept CD changer

If your car falls into the above range and has Navigation, CD changer or iPod connection, GROM will work without any reprogramming

Step 1 - remove the factory head unit (see FAQ's or video clips for further help)
Step 2 - connect the Data Cable (Vehicle Specific Cable) into the typically empty CD changer port on the rear of the unit. 
Step 3 - plug the other end of the data cable into the Grom interface which is small enough to leave behind the stereo or ideally route into the glove box.
Step 4 - Install head unit and enjoy!

  • No fuss, easy DIY plug-and-play installation
  • No wiring needs to be cut or soldered.
  • The installation of this kit should not affect your vehicles warranty.
  • 0.5m Data cable (vehicle specific cable)
