Yes indeed, if you download (or already have) Basecamp then you can download Mapsource from Garmin. I did this recently on my traveling notebook which has limited memory and because of that I deleted Basecamp once I had Mapsource working
Does anyone know of another link for mapsource as this one does seem to work for me. I had some software issues on my PC and am having to do a complete reinstall of most of my software.
