I have a Nuvi 200 that I have successfully added Michigan Topo maps from this site to and plan to use it on my ATV. Reading on Garmin's website, after a ride I can hook the 200 to my computer and look at the track of where I have been. My question is can I add the track to the topo map and save it for future reference. What I would like to do is build a mpa with different trails on it. I also have a Garmin legend I could use, but my eyes aren't what they use to be and the display is quite small.
