Had a odd problem today. No audio whatsoever. No audio from Radio, Sat NAV woman, Voice control system, Bluetooth phone, BMW Assist ... even seatbelt warning chime or low fuel warning.
The car was deathly silent, other than the engine. I needed to stop for gas (typical, as its a M3
) and when I returned to the car after a few minutes, everything was back to normal.
I guess one of the systems didn't start up correctly. Keep a eye on it, and hopefully it wont be a problem that returns.
