I just finished a search for information on creating .crs files for my Edge 305.
Of the many free online sites, Toporoute.com does a good job when coupled with GPX2crs.
But I keep reading about using ST being used to create routes. I've yet to see how this is possible. Am I missing something? Can a route be created from scratch? Or are folk talking about the ST edit function on existing routes?
Seems to me that ST is useful after an activity, not before it.
