SL/R231: lost sound
when i would touch the mute the message "microphone on" or "microphone off" would be displayed on the screen.
Then the only way to get sound back was to reset the system-and you then loose all data (seat position, radio stations etc.)
What i have done now to restore sound is turn off bluetooth on my phone-I now have sound but no bluetooth phone connection.




I would remove both Bluetooth pairings (phone & MB) and re-pair just to be sure...
