    • No. Everything should be in the car. MMI 3G unit itself is equipped with bluetooth receiver, the microphone is also in the car for the GALA (noise volume adjustment).

  • Hi. I have an issue with my Bluetooth. It used to work but it just stopped working some time ago. I cannot connect the phone (any type of phone) to the car anymore. My firmware is quite old, BBT_EU_P0020_D1 and I read that there is a problem with this firmware, someone wrote in a forum that it should be updated using the firmware P0020_ADJBK_FIX. I couldn’t find this version anywhere. Do you have it? Thanks.

  • Hello,
    this is valid for MMI 3G system or is valid for 3G MMI PLUS system, thanks

  • Hi, I have a 2009 Audi Q5 with MMI 3G. Is it possible that the bluetooth is already installed and only neads activation? I tried to access the hidden menu but it wasn’t possible. Is there any links for reliable VAG-Com cables?

    Thank you

    • If you have MMI 3G, then you have bluetooth preinstalled. It’s that simple.

  • Hi, it seems that my 2009 Q5 has the MMI 3G Plus system. Should it have the bluetooth pre installed and just needs activation?

    • Yes. But i believe that 3G+ system is too fresh to be installed in 2009 car.
