Can anyone recommend a decent gps for off road travel in the USA?

I went with the Dual puck and Trimble Outdoor Pro application, with Navionics for the boat. It seems to work nicely.

Here is the "ebay Bluetooth module". I bought mine awhile ago, and Got a better price than this one. But I think I may have paid shipping and it evened out. Either way, its cheap and works great.
