I know its a sin but I have the 24K West Topo maps and am wanting to overlay NW Trails into Garmin's basecamp. I'm guessing that I could upload it together with the .gdp created in basecamp to affect my desired end result (have NW Trails as overlay on garmin) but I want to see it in basecamp on top of the other maps for route planning.
