I'd like to thank Boyd, Oz, and the others who helped me on "running gps with a laptop". I just returned from a 4600 mile road trip using a gps purchased for fishing on Northern Idaho and Montana. I used n-route as suggested by Oz and later Garmin and it worked perfect. I had a little trouble with mapsource, using my wife's laptop with windows 7, so downloaded version 6.13.7 as suggested by freecat with a "windows 7 mapsource tip". It crashed also after a while, so went to Beta as suggested in the using maps/Garmin software forum. I had 2 problems with it but with all the help, my wife and I made it the whole way from North Idaho up by Canada to SW Nebraska to central Indiana and back again thru snow storms and road closures in Wyoming, thunder storms in every state I think, heavy winds, and worst of all big cities, I like mountains and trees, not a lot of people and traffic. But we made it and visited both kids, and got back about 2 hours ago. 4600 miles in less than 2 weeks. This site helped a lot. Thanks again.
