GPS tech (Garmin, Hammerhead, Wahoo, RWGPS, etc)

I've added gpx files before and they don't give turn-by-turn warnings. It may have been because I didn't enable them but I've always run files through bikeroutetoaster until now.

When people do not get turn by turn directions as you intimate it is because this has not been enabled in the course settings.

For general info this is not a global setting and turn guidance needs to be set to on, individually for each course.
