I've tried the auto route on the 830 a couple of times while traveling and it's done a great job of finding me a ride that was bike friendly. However, on the second ride it routed me on the bike path but the path was temporarily closed for road work. Luckily it was close to my starting point so I knew how to get around it.
Is there a way to skip a portion of the auto-generated routes or tell the unit to reroute around issues like this?
