When data is available, a route is searched
for based on prior statistical data relating to
the day, week, and time. (See page 141)
The route may change drastically when real-
time traffic conditions are factored in.
If you leave the route that was searched for
based on your current position, and new
information is received regarding traffic
conditions for the recommended route, the
software automatically searches for another
route.
See “Route Settings” on page 148 for
detailed information on Route settings.

the GPS receiver, the signal is too
weak to measure the GPS.
Cannot perform GPS navigation.
Only a few satellites are transmitting.
Positional information is available,
but altitude (elevation above sea
level) cannot be calculated.
GPS navigation is possible, but large
