I know a few on here (mlord, for one) does GPSin' stuff (cachehunting. etc.). I FINALLY nailed down a cable to connect my old, old Garmin to my Palm. I have software on my Palm where I can feed it a co-ordinate and it'll tell me how far I need to go, etc etc.

Fine and dandy, however, I was wondering if anyone knows of any Palm app that combines that with an actuall USGS Topographical map. So instead of just showing me an arrow pointing 'up', I can have an overlay of a topographical map with the arrow pointing up. (Or, at the very least, the topo map and a different screen with the arrow..)

Commercial or freeware, anyone?

Thanks!
Mike.
