Faster time—routes calculated are faster to drive, but can be
longer in distance.
Shorter Distance—routes calculated are shorter in distance
but can take more time to drive.
off road—creates a direct line from your current location
to your destination. This is useful when you are travelling
outside of detailed map coverage areas or where no roads
exist.
ask My preference—determines whether you are asked to select a
route preference before route calculations.
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 more time to calculate, but
generates a better quality route.
Better route—generates an even better quality route, but
uses a longer calculation time.

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;
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. Refer to page 62 for
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 especially nice if you
want to avoid major highways, for example.
