I would like to down load maps of CO for my etrex, but don't know much about GPS. Anybody have source for that?
This what I use www.huntinggpsmaps.com (http://www.huntinggpsmaps.com)
Putting maps on your eTrex happens in 2 parts:
1. Download map and open in a program called Garmin Basecamp.
2. Connect the eTrex to the computer and transfer the map to the GPS using Garmin Basecamp.

The trick is getting the files to open in Garmin BaseCamp.
