I could really use some help with my 2008 MMH. I bought the vehicle about a month ago and the navigation feature did not work on the vehicle. The owner acknowledge that before I bought it.
When I try to turn on the Navigation System I get an error that says something about "an incompatible disk" and inserting a new disc.
The navigation system is software v3.0, but the DVD is for v5.0. Could this be the problem? Are there any software upgrades that I might need?
Thanks in advance,
