C55 Radio Low Volume
It sounded like a single channel single speaker.
I lost use of phone and voice control as well...
Turning the dial and using the steering wheel controls did nothing.
I ventured to the dealer, and there they “updated” COMAND manually with 3 or 4 CDs/DVDs. It didn’t immediately return...but, about 20 minutes into the the drive home, it kicked back on!
