Simple question: How do I use tcx map files (or other map files) with Foreruner 310XT? (if it can use them)
And by "use" I mean import, and start the route on the 310XT.
I really hope some of you use tcx files and know how to do this. I have had XT310 since it came out, but have never figured out how to use a route planner with it.
