2002 slk 32 AMG
The other night my cd player went out. It stopped playing and the radio came on. When I tried to switch back to the cd player I got a message that said "cd player not found', or something to that effect. The next day I noticed that both power seats had stopped working. These problems couldn't be related, could they?

 

Probably not related. Cd changers typically fail exactly as you described, refurb units avail through dealer. I am not sure on the seats though. It may have a convenience relay like in a w202 chasis, can't remember off the top of my head though. message me if you'd like further info so I can look it up.
