I have tried using Google Earth coordinates (rolling the cursor over a location) with my Garmin eTrek H. I changed the settings on Google Earth to match what I thought would match the coordinate system of the Garmin. Well, at least the number of digits matched. I wrote down the lat/lon and then entered them into the Garmin following the instructions in the owner's manual (an online resource). Once out hiking I tried "Go To" one of the coordinates. I knew I was within a mile of the location. The Garmin said I was 21.5 miles away. Any suggestions?
