I was wondering if anyone has had their GPS module go out and, if so, have you replaced it yourself. Does the module require any sort of programming? My GPS module went out after having the car only two years. It cost $795 to have the Navigation feature added to Sync to begin with. Now the dealership wants $700 just to replace the GPS module that has quit working. (car out of warranty by 6000 miles). Obviously the Navigation is useless without a working GPS module. Any help or advice is much appreciated. Thanks, Robert M.
