Anyone willing to part with a NE Nav CD?? I'm having trouble with my 04, it doesn't seem to want to read the CD. When the disc goes in it sends the radio into convulsions. I'm hoping it is not the head unit. The other ones don't do that, but I still can't tell if the system is working or not. The best I can do is trace the start of the problems back to a trip to the body shop and the CD was in the head unit when the truck got baked after paint. Of course the only CD I need is the one that doesn't work.
