I tried to export a friends ride and follow it. It's a nice circle and he lives a bit from me, so I just wanted the 820 to start following it from where I enter the circle, so to speak - ie not starting where he did.
However, I couldn't find a way to do that.. either the 820 tried to guide me to his home to start there, or it tried to recalculate the route which took ages and didn't work anyway. I never got it to find the route despite spending 30km on it... dismissing all the "Recalculate route?" messages except one, which also took ages (10-15 minutes!) but didn't work.
What am I doing wrong? Does navigating a route require me to start at the exact starting point or is there a setting I missed?
