@Bradmax: try pressing the eject button like crazy. This happens sometimes but should not. Keeping pushing. Try holding the button or push it fast and often. If you get the disc out, disconnect the battery for 10 minutes this helps sometimes with eletronic trouble.

Regarding TMC & V27: the TMC is not "broken", it just has to be reassigned in the setup menu of the radio. Happened to me as well.
