Prefer/Avoid Toll Roads
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
T

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.
Prefer/Avoid Interstates
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
I

STATES
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.
Turn Preview
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.
A Turn Preview screen is shown above. If you are navigating in one of
the two satellite map modes, the turn preview will still look like the
above figure. The Turn Preview screen will not show your turn using
satellite imagery. The Turn Preview screen always shows your turn in
the regular map screen mode.
