HELP! Very LOUD feed back
I own a 2011 CLS550 recently my audio system has been malfunctioning. Every few days there is a VERY<VERY loud feedback static hum coming from the driver's side rear speaker. It is not affected by the volume control, If I turn off the car it continues then goes away when I close the door. Also, sometimes when I turn on the audio system there is no sounds when I switch between the CD player and radio I get an error window saying "device unavailable" I'm puzzled.
