I finally got it. I am not sure what was wrong but I got on Garmins website and learned how to do a total unit reset. After that I used mapsource to upload the topo maps again and it worked perfectly. It is really a beautifully done map. I was starting to regret my decision of not buying to the 400t but now I see it was the right decision. I want to go hiking now but it is only 15 degree F right now...
