| Driving to work listening to Led Zeplin I. Stop at Starbucks for a cup of coffie. When I start the car all audio in muted with the speaker on the display unit crossed out as if I had muted the audio. Unable to unmute audio. Turn off and restart car twice. Audio still muted. Park car for a couple of hours, restart, everything working fine.
I talked to the service manager at local BMW and he said that if it happens again to let him know and he will make an appointment to reload the software on the car.
