I have been checking around and I can't seem to find any specific off road DVD disc
I can use in place of the stock DVD disc that comes with the factory Navigation,
on my 2007 H3.
What I want is a DVD that covers off road trails and such just like a topographic map.
I have found that the stock DVD disc will get me some, but very limited info for off road.
I can buy topo maps at the standard 1:24,000 scale of national parks and other areas, but not in DVD form.
I often go up to the Toiyabe National Forest in central Nevada and have used maps for this area, for years.
It would be perfect if I could use my H3 navigation system to help me on these trails
Does any one know of any source for DVD discs that will work in our nav system
My hand held Garmin has topo maps and shows my where i am.
And i have called Hummer USA, GM and Navteq (makers of our Nav head units) and no luck
Can I be the only one who is interested in this ??

Thanks
