Apache_1

Went to update (Mercedes issue NavMaps) and process stopped at about 3%. Nav System calls for Disc 1 but when loaded, get message ""This map update is not possible. Ejecting DVD. Refer to the Operator's Manual". Then (repetitive and the same result) "Please insert Navigation update DVD No.1" ALSO, even though I can load and play a music CD, the system will not play Video DVD even though it "reads" the title of the movie. Everything was working OK until this update attempt.
Thanks for anyone who has specific experience with this kind of problem.

Run a CD cleaning disk in there, in case laser got dirty.
