Routing Options
Routing Options are used to control exactly how the unit
generates a route from your current position to a selected
destination.
When generating a route, the unit can analyze certain types of roads or
turns and adjust their value to prefer or avoid them. Preferred road
types will occur more often in your routes. The unit will deliberately try
to take those types of roads.
The Avoid on Routes screen.
Roads or turns that you choose to Avoid will show up less, although the
unit may have to generate a longer route to avoid them. The three slide
controls in the Avoid on Routes screen allow you to control how much
you want to avoid or prefer the associated options when generating a
route. The farther you move the slider to the left or right, the more it
will affect the routes generated by the unit.
If you change these values significantly and notice the unit has begun
generating poor routes try using the
RESET TO DEFAULTS button to see if
that helps. You can use the
RECALCULATE ROUTE button to automatically
generate a new route to the same destination using the new prefer-
ences. Take advantage of this option when you are trying to learn the
right amount of avoidance to make sure the unit gives you what you
want.
Avoid Cross-Traffic Turns
Use this option to avoid turns across busy lanes of traffic. The unit will
not avoid cross-traffic turns at major intersections where you will likely
have a protected turn at a traffic light. Sometimes you would have to
drive miles out of your way to avoid taking a cross-traffic turn some-
where in your route. Then again, sometimes it's worth it. Practice with
this setting to find the value that's right for your driving experience.
