I am basically using it to follow routes created on the Fugawi UK OS 1:50,000 desktop software.
However, I have one problem that I find irritating:
If the route turns a corner (anything more than about 70 degrees), the away from route alarm sounds 80m after making the turn, and keeps sounding until I am 160m from the turn [80m and 160m are the min and max distances I have selected for route alarms].
If I check my GPS position, it is bang on the route. So why am I getting an alarm? I want it to tell me when I really am off the route, but not every time the route turns a corner.
