Hello, I have a Audi A6 2010 with MMI 3G, in the mechanical workshop changed me the two modules of radio.
After this, I have problems with bluetooth. When I press TEL button, it says, “Bluetooth is not activated, would you like to activate it now”, I press yes button, it will search for a while, around 5 second, and tell “no Bluetooth devices found”.
I update the firmware, now I have HNav Eu K0257 ...
