I'm doing a trek in Patagonia in January and since there are no Topo maps for the area available (from Garmin) can I buy the Montana and load waypoints for the trek and just follow them on the Montana without loading any purchased maps?
Considering this as a backup to my compass.
Check with these guys they have remote maps like this one for Chile: http://store.gpstravelmaps.com/Chile_p/chile.htm
