Last day of Skyline to Blue ridge trip, Used Tyre to plan entire trip, What I have learned about HD GPS and Tyre:
Plan your route from your location to end point, when done, move start point a distance on the route away from start point. If you do not and GPS is not EXACT on your location, the GPS will keep re routing you back to start point, I circled Roanoke twice to get back to hotel even though I started from there, GPS was only off by yards, but it was south of parking lot and we were heading north, Do not use "avoid" feature on HD GPS, it changes your route, Hit the three lines on right of map screen and there is an option "cancel next waypoint" The GPS then takes you on your planned route as inputted. DO NOT cancel the route to add another stop on the way, if you re load the route, it takes you back to start point. I was able to avoid next few waypoint to continue on my planned route, but that is a PITA. Find your POI and add it as a stop, once there (Re: gas) the GPS will return you to your route as you planned it. All in all, it worked well once I learned these tricks.
Maybe someone has a way, I searched and could not find it in Tyre, but anyone know how to avoid non paved roads? I planed a few twisty's and on 3 occasions, they took me down gravel roads, that sucked. Anyone know how Tyre can avoid these roads?
