HI,
I've a 2003 C Class Coupe with a cd changer in the golve box, how do i connect to the head unit, the handbook say's there should be a command via the steering wheel commands. The command only recognises the single slot cd ??
Any idea's

 

When your on the CD menu like so try hitting 1 or 2 or 3. Does that work?

Did you just buy the car or did it stop working?

 

I've recently purchased the car, its got a more basic head unit, not the one your reply..
I've tried selecting 123 etc but it makes no difference.. (

 

You should have an Audio 10. The CD shuttle is connected by fibre optical cable. Remember to activate the shuttle vs. the single player you need to push the CD button twice in quick succession. The Audio 10 is a darn good unit.

Better sound than most.
