Our system keeps saying the dvd is corrupt or dirty.We have cleaned it and it still doesnt work.Do we need to get a new dvd or have the system serviced? I would hate to spend $200 on a new disc when it is a system problem.
Had the same problem. Took it to the dealer and they reported that the navigation unit needed to be replaced (which they did under my extended warranty). You could try a new disc, but that did not work for me.
