How do u change your deteremined route to use mainly highway? ive noticed my navigation usually brings me through some backroads when i know thers a highway that would take me there quicker? prob a newbie ? but im retarded.. lol

 

After you've set your destination, push ROUTE and choose ROUTE PRIORITY, and in there you can choose 1/ fastest route, 2/ minimize freeway, or 3/ shortest route.

Enjoy.....
