Calculate a scenic route on a zumo 350 and 390

To calculate a more scenic route on the zumo without creating a custom route, adjust the avoidances for major interstates and toll roads. This will cause the device to calculate routes on smaller highways and secondary roads, which are generally more scenic. 

To change the Avoidances setting:

1. Touch Settings
2. Touch Navigation
3. Touch Avoidances
4. Touch Highways and Tolls and Fees to place a checkmark next to them
5. Touch Save 

After following the above steps, the zumo will avoid larger highways, and should provide routes on smaller, more scenic roads.
