Perhaps it was the CD. I told the owner to go ahead and burn another and make sure it plays in other sources then try it. Interesting enough that the donor CCC is a 2005 or 2006 in my 2004. But my 2004 was also pre-wired for navigation. Were there 2005's that were actually pre-wired for navigation? I think his production date is 09/2004....he definitely has an M54 engine.
