I have a Garmin 60csx, and I do a lot of camping and scouting. Usually my wife comes up later and can’t find me and there is no cell service where I go. I bought another gps unit for her which is a Garmin 760. The question is can I load topo maps in it and have the forest service roads show up to get her to where I am, I have contacted Garmin and they said I could do it but the topo contours would not be visible. I don’t care about the contour, I am interested in the back roads. Any insight and/or experience would be appreciated.
