Did you get the MapSource/basecamp upload/download software with your rino?
There a are few background maps you can use with MapSource
Like just the basic map that came with Mapsource or ETOP Canada or BackCountry Maps
The better the quality the bigger the price ETOP $100.00 but Backcountry Map AB/BC is $275.00
Is it just the maps or tracks/Waypoints too that you are looking for???
Snow and Mud will not allow a Garmin GDB file to upload but if you need the tracks and waypoints then PM me with your email address.
