This is my dilemma I have a BMW K1200LT 2005, with a Becker professional radio/CD. I had some problems with the radio and had it repair at the Becker Auto Sound Shop in NJ. They installed a new mother board with the proper program. Now I can hear a radio station but I have no control in changing either the radio station or the volume- it does not response, also the radio shutoff after 20 t0 25 seconds after is turn on. Can anyone give me an advice? At this point I’m at lost, I have trace all wires and check all harnesses and seems to be OK.
