Preference setting for all route calculations. This setting is recommended if you usually have the same
preference for your routes.
Calculation Method
– Allows you to control how thoroughly the StreetPilot searches for the perfect route.
A trade-off exists between the length of time the unit takes to fi nd a route and the quality of that route
(given the calculation criterion selected under Route Preference settings). The following options are avail-
able:
• Quickest Calculation: This calculation returns the fastest results, but it might not fi nd the best route.
• Quick Calculation: This takes a bit more time to calculate than the ‘Quickest Calculation’ method,
but generates a better quality route.
• Better Route: This generates an even better quality route, but uses a longer calculation time than the
‘Quick Calculation’ method.
• Best Route: This generates the most optimal route, but takes the longest time to calculate.
Calculate Routes for
– Lets you take full advantage of the routing information built into the StreetPilot’s
mapping software. Some roads have vehicle-based restrictions. For example, a street or gate may be
accessible by emergency vehicles only, or a residential street may not allow commercial trucking traffi c. By
specifying which vehicle type you are driving, you optimize the route for your vehicle type. Likewise, the
StreetPilot may give you access to roads or turns that wouldn’t be available to normal traffi c.
Avoidance button
The Avoidance button appears on the Routing tab and allows you to avoid certain road types that may
be undesirable on your route. The StreetPilot will use these road types only if alternative routes take you
too far out of your way or if no other road is available.
• U-Turns: If checked, the StreetPilot does not direct you to make a U-turn on non-divided highways.
• Toll Roads: If checked, the StreetPilot avoids entering toll roads.
• Highways: If checked, the StreetPilot avoids routing you along interstates and major highways.
• Unpaved Roads: If checked, the StreetPilot avoids unpaved surfaces.
Using the ‘Calculate Routes for’ option allows you to
take full advantage of the routing information con-
tained in the StreetPilot’s mapping software for plan-
ning the most effi cient route for your type of vehicle.
The following options are available:
• Car/Motorcycle
• Truck (large semi-tractor/trailer/lorry)
• Bus
• Emergency (ambulance, fi re department, police, etc.)
• Taxi
• Delivery (delivery vehicles)
• Bicycle (avoids routing through interstates and major
highways)
• Pedestrian
