    The screen for the audio electronics says DEVICE UNAVAILABLE, and none of the audio electronics will work. This can happen at anytime, when you are just starting up or driving down the road. I have recorded this on my cellphone and showed it to the Mercedes service department and they simply said they could not duplicate the issue.
