I guess the maps should download OK using the methods in this thread but is StreetPilot user friendly for off-road navigation when you dont really need auto-routing but want more traditional gps sight-and-go?

Anyone given this a go?

Topo maps work perfectly, even 3rd party tops, just make sure you make a gmapsupp.img file, unlock it and put it in the SDcard folder in Library. The Canada Topo v4 even shows DEM shading, which is nice.

I tried putting the gmapdem.img file for North America in the main .img folder, but it doesn't seem to be recognized. DEM does work, but only if it's embedded in a map?
