I have a 2003 X type with Navigation system. I was having intermittent issues with the CD player. It would work fine for awhile, then it wouldn't. I would hit the "CD" button on the dash unit and get a "CDC Error" message. Now it does nothing. Also, the navigation works fine, but there are no voice commands anymore. I was told that its not the CD player, but the entire unit needs to be replaced at a cost of almost $3000. Obviously, I hope to find a cheaper fix, if possible. If I find a used unit online, how can I be sure the unit will work with my car? Is a unit that comes out of another 2003 X type compatible? Or do I need to have more information? Also, is this something that I would have to take to the dealer to get installed? Thanks for your help. You guys have helped me before and I appreciate it.
