Final input to this adventure. I went to work on my 96 DD to see if I could retrieve the hostage CDs in it that would not release with the battery cable disconnect method.
What I did, (thanks to 95 Mk Vlll),was to remove the whole unit from the trunk by removing three screws that held the CD frame to the car body. After removing the six screws Phillips that held the bracket to the CD player I then removed about a dozen small Phillips screws around the CD player cabinet and slid the guts out. There is a small component board that is held in with about 6 tiny Phillips screws and I removed them as well as I learned there is a large drive wheel that should be rotated in order to free the cartridge. As I was removing this small component board the cartridge unit popped out. "Free at Last, they're Free at Last". Thanks guys for all the suggestions I hope this thread will help someone else in the future.
