Basecamp is a free download from Garmin and their new supported software. http://www.garmin.com/en-US/shop/downloads/basecamp Good tips on using Basecamp in this thread... http://advrider.com/forums/showthread.php?t=899796 Mapsource is being phased out and while Basecamp isn't quite as good as Mapsource, it's getting there. Some old Mapsource users complain about the basecamp interface but like anything, spend some time, learn it and it can be a useful tool. I'm fortunate I guess in that I never learned MapSource, I used to spend all my time in Delorme Topo and if you can figure that software out you can figure anything out. Quirky but powerful.
