System Setup
Reference
Routing File Tab
The Routing Tab allows you to customize the routing features of the StreetPilot III.
Route Preference—Determines what criteria are used for fi nding the route to your destination. The
following options are available:
• Faster Time: This setting causes time to be used as the criteria for calculating your route.
The routes calculated with this setting will be faster to drive but may be longer
in distance.
• Shorter Distance: This setting causes distance to be used as the criteria for calculating your
route. The routes calculated with this setting will be shorter in distance but
may take more time to drive.
• Off Road: This setting causes your route to be a direct line from you to your destination. This may
be useful outside of detailed map coverage areas.
Calculation Method— Allows you to control how thoroughly the StreetPilot III searches for the
perfect route. There is a trade-off here between the length of time it takes
to fi nd a route and the quality of that route (or how close is to the ideal
route as determined by your Route Preference setting). The following options
are available:
•Quickest Calculation: This will give you the fastest results, minimizing the time you have to
wait.
•Best Route: This will cause route calculations to take somewhat longer, but you will get the
best route.
The ‘Ask Me My Preference’ setting can also be changed
from the Routing File Tab.
Using the ‘Calculate Routes For’ option allows you to
take full advantage of the routing information contained
in the City Navigator Maps for planning the most effi -
cient route for your type of vehicle.
