Lalique,
I don't have the answer to your question but look forward to any reply, because I am having trouble downloading waypoints from other sites into my GPSmap60CSx. I also have Trip and Waypoint manager software, also MapSource software for TOPO and City. I would like to do this via a GPX file which I understand is a standard format. I would like to download routes as well. Also from sites like www.trails.com and geocaching.com.
It can't be that difficult. What am I doing wrong?
David
