I have snow leopard, and use roadtrip (mac equivalent to mapsource) and I was wondering what the point of basecamp is? I know it is used for topo maps you buy that have DEM shading for units like the Oregon, or others. I have a gpsmap 60csx, and I use the amazingly sweet and free topos here. Can the free ones here even be used on basecamp? is the only benefit the DEM shading (since gpsmap 60csx can't see it anyways) am I completely wrong is is there no real point to basecamp?
P.S. sorry if there is a similar thread I missed somewhere.
