Sounds like a PITA to have to upload that often. I wouldn't even consider carrying a laptop and finding a system along the way every time you needed one that would let you install GPS software doesn't sound feasible. Has anyone here managed to load a trip like the TA or the NT all at once? I read some rumors that it has been done with some trickery involving track points or POI's instead of waypoints. Apparently they have a much less restrictive limit.
