I had similar problems with the in dash 6 CD changer that came in my '05. Dealer said to bring it in and they would change it out. They are a crappy design and I think the problems are common. I yanked the stereo myself and put it into an '04 I traded in for the '06. The '04 system is much better, IMO.

Bring it in - I'm sure they'll just replace it.
