I just got my Garmin GPSMAP 62S. I like it alot so far, but the directions leave alot to be desired.... I'm trying to figure out how to download some topo maps to it.....
You need to buy the software for the topo maps if it doesn't come with it. It doesn't have to be mapsource but I don't have any other experience with anything else. If you get the software, I might be able to walk you through.
