It would be worth a shot, disconnecting the battery has resolved one or two issues in my 05.

I've always had good luck with Memorex CD-R's, and one trick I learned if your burning software has the option, is to finalize the CD once you're done burning. You can't add songs later obviously, but it seemed to make the CD's play in more devices.

Are you burning audio CD's or MP3 CD's? I'm almost certain it's either a formatting error or maybe the brand you're using. Abc up there makes a very good point, some CD's sold for home use and burning are just not within the tolerances of all players.

Worse come to worst, aftermarket head unit? ;D
