By default, toll roads have a fairly high value in routes generated by 

the unit because they are usually quality roads with high speed limits 

allowing you to get where you are going faster. If you would like to save 

on the cost of traveling toll roads consider setting the unit to generally 
Avoid toll roads by pressing and dragging the 

 slider to the 

right. If you want to drive free drag the slider all the way to the right 

and the unit will not use toll roads at all. If you prefer the convenience 

of toll roads, and don't mind the cost, you can give them an even 

greater value by pressing and dragging the slider to the left. 

Interstate Highways may not be as expensive to travel as toll roads but 

sometimes the stress of merging and exiting, combined with the high 

speed, make interstates less attractive – especially for short trips 

across town. The default setting is designed to avoid Interstates for 

very short trips but if you feel like it's sending you to the highway too 

often try setting the unit to Avoid Interstates. Press and drag the 

 slider to the right. Like toll roads, you might prefer the speed of 

Interstate travel. You can set the unit to prefer Interstates by pressing 

and dragging the slider to the left. 

The Turn Preview checkbox allows you to select whether or not the unit 

displays a Turn Preview screen whenever you approach a turn in your 

route. A Turn Preview is designed to prepare you for upcoming turns. 

You can access the Turn Preview for any turn in a route by going to the 

Directions list.
