I have a 01 cls 5at, and lately when i put it into reverse, the passenger side mirror won't tilt down like its supposed to. sometime it does, but most of the time, it doesn't.... any one have any clues on what could be the problem? any help would do. thanks.

 

no idea. But i also have no idea what this has to do with audio/video.

 

Your mirror adjust switch needs to be in the middle. Not on RIGHT and not on LEFT. In the middle where there is a pic of the mirrow with a down arrow.
