If I an on a route with multiple points and want to add a via point it puts it into the route where you have to manually order the route instead of it adding it where it should go. My 765 automatically adds it to the proper place in the route. Do I have a setting off? Surely this unit is smarter than that.
Try posting at this site http://forums.gpsreview.net/ I usually get better answers for nuvi questions there. This Garmin site is more for sport activities.
