I have been thinking of using this model for an ATV GPS. I always have power, so that's not a problem. The big screen is a plus for us old guys. I have been looking for a cradle for the 5000 but haven't seen one. The standard ball and socket is a little weak for ATV use, but I suppose I can stiffen it up.
I haven't bought any topo maps from Garmin, I'm wondering how mush detail they have. For MapScource, I've been using a topo I got this site. Works pretty good, but doesn't show whether an area is private property, BLM, State, or National Forest.
Thanks for any input.
