How's the NAV System?

[Hummer Guy]

The database is DVD based and is updated yearly. "Secondary" roads can be a lot of things, but I've found that this has some pretty obscure places and roads I wouldn't expect. If you're looking for a spot in particular, you can always set the map to that area at the dealership and see if those roads are present. Same with 4WD roads. There is no altitude indicator in the H3.
