I have created a route in Basecamp (for going on smaller roads by car), and a track from the route. The simulation works fine in Basecamp. Then I send the route and the track to the GPS (Garmin Nuvi 3490) the route looks correct. But then I try to follow it in the car the GPS optmize the route and wants to take the fastest way. Are there some algoritms that is possible to disable? Or how do I avoid this problem? /Thanks Sabina
