I was up in the Lake Tahoe area and the NAV system only had MAJOR highways. Once I arrived in any of the smaller towns there were NO ROADS at all on the map and it said "OFF ROAD" - not good. I'm going to call NAVTEQ and see if there is an update.

Does anyone know if it is possible to use a different BRAND of NAV DVD in the PCM? My buddy was traveling with me had his Range Rover and it showed all the small towns and little roads...
