I chose Saved Courses, picked my course, and pushed off.
The problem was that half way through what was supposed to be a 14 mile course I suddenly got a message saying "Lost active route", and it automatically ended that course. I had go back to the main menu and choose my saved course to restart.
I have Autostart set at 6 seconds, but no other settings that stand out. I was riding along a road with woods on either side, so is it possible that GPS lost my location? If so there was no indication to that effect.
Any help would be appreciated
