How's the NAV System?

[Michael1]

I wanted to see if people are happy with the H3 NAV system. Any problems?

Also, does it have a off-road bread crumb system like the LR3's, and the 2007 Wrangler?

H3 Nav is good -- you can use both CD and Nav disc at the same time (unlike the H2 nav)

My understanding is that the H3 Nav does not have the breadcrumb option that allows you to see a line marking the path you've taken. Isn't half the fun of off-roading finding a way back from the middle of the woods?:)

How is the database? Does it show secondary roads? Does it show 4WD roads and your altitude?

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.
