Windows 10, Basecamp v4.7.5
When I attempt to convert a track (with many points) to a route, I get a route with only the start and end points, which are the same place. The route says it's 250 miles, but there are no directions, just the two points. This happens most of the time. Sometimes, for reasons I don't know, it kind of works. I've tried switching the route options and that doesn't seem to have an effect.
I've tried deleting all the points in the track (read this online somewhere) and creating a route, which again results in the 2-point route.
Occasionally, when it kind of works, the route skips around places where it thinks there isn't a road, instead of there being an option (that I can find) to force a route segment between 2 points. This seems to be because Basecamps maps are missing lots of smaller roads, at least where I live.
How do I create a route that matches a track exactly, turn by turn.
