Magellan is the way to go from what I've read. I just haven't dropped the $ on one. I think I may soon though especially if we start backpacking more, would be fun to record our trip and plot on the computer
I do that for everything. It's extremely addictive.
I've done that with all my Garmin units -- GPS V, Geko 301, GPSMAP 60CSx and Nuvi 760. I'll stick w/ Garmin for compatibility with the software that's already on the computer.
I`m not saying you can't do that with garmin.
My garmin's have had terrible reception issues in cloud cover, light trees, snow, etc, if I was lost they didn't help. Playing around they were no use. Thus no good.
