This is great video/player for the visual individual who wants to load maps to his Garmin Mapping GPS using a PC or Mac computer.
http://www8.garmin.com/cartography/mapsourceTutorial.htmlYou can watch it on your screen or save it to your hard drive. Do not select the Mac if you are a PC user. It will put you into the Mac world and getting out is minor pain. I selected Mac to see if I could gain some knowledge and two key clicks later I wished I had not.
The options are clearly labeled.
