Calculation Method—sets how the unit searches for the route.
• Quickest Calculation—calculates the route the quickest, but
it might not produce the best route.
• Quick Calculation—takes a bit more time to calculate but
generates a better quality route.
• Better Route—generates an even better quality route but uses
a longer calculation time.
• Best Route—generates the most optimal route but takes the
longest time to calculate.
Calculate Routes for—sets route calculation for the particular
vehicle you are operating to optimize the route for your vehicle type,
as some roads have vehicle-based restrictions.
Avoid—allows you to avoid certain road types and maneuvers on
your route. The unit uses these road types only if alternative routes
take you too far out of your way or if no other road is available.
Custom Avoids—allows you to enter specific areas and roads
that you would like to avoid in your navigation. See page
information on creating custom avoids.
Custom Road Prefs—allows you to avoid or use Major, Medium,
and Minor roads using a slider scale. This is useful if you want to
avoid major highways, for example. Select Auto Set to use preset
values.
