Please help - After mechanic replaced Parking brake module, speakers no longer work. He says it cannot be related. No chimes of any kind, No Navigation audio, no radio/CD, Aux. I did check all the radio fuses. Can you recommend BMW electronics specialists in Philadelphia, PA area
If the navigation screen is dead sounds like the CIC has gone down. This can bring down the whole fiber optic network and the sound. If he replaced the parking brake module programming for the module had to occur and could have caused the CIC to crash. Can always try to recover the module but if not then needs to be replaced.
