Looking at your post, you say "mapping software"
rather than how to find streets, etc.
I use a Delorme Earthmate, mounted on the roof in a weatherproof enclosure to give far better satellite acquisition, tied into a laptop, and use Delorme's TOPO 4.0 as I am interested in mapping and where I am going in the boondocks, and also hiking in the national forests, Parks and BLM land when I get there. I can print out topo maps of the areas I want to exlpore before we go
