Got a Garmin eTrex for the holidays and have been learning to use it. Have been out caching a couple of times and love it, so does my wife luckily.
My question is, I have downloaded some maps but do not know how to read them. The file formats are .dbf, .sbn, .shp, .shx
I would like to download some good maps and be able to add waypoints to and from my GPS. I know the eTrex does not have mapping capabilites, but this would help plan trips and locate waypoints I have collected out in the field.
I am very new to GPSing and short on expendable cash... baby, house, etc., etc.
What I really would like is a freeware, shareware program and a way to find some online maps.
I hope I am not missing something too fundamental.
Thanks in advance,
