Frequently Asked Questions
Guidance, Routing
Problem Solution
The navigation does not route me the same way I would go, or
the way some other mapping program displays. Why is this? The navigation system attempts to generate the optimum route. See
Changing the Routing Method on page 52.
The navigation wants to route me around potential traffic
problems. How do I stop these pop-up messages? This feature can be turned off. See Traffic Rerouting on page 105.
Why is the street I’m on not shown on the map? It has been
here for more than a year. The mapping database is constantly undergoing revision. See page 126 for
ways to obtain the latest detailed coverage information.
The vehicle position icon is not following the road, and the
“GPS icon” text in the upper left hand corner of the screen is
white or missing. • The GPS antenna (located on the driver’s side of the rear shelf) may be
blocked by personal items. For best reception, remove items from the rear
shelf, such as radar detectors, cell phones, or loose articles.
• Metallic tinting or other aftermarket devices can interfere with the GPS
reception. Please see your dealer. Also see System Limitations on
page 119.
I entered a destination, but the blue highlighted route and
voice guidance stopped, or turned into a blue/pink dashed line
before I got to my destination. Why is this? Your route has entered an unverified area. See Unverified Area Routing on
page 101.
The map rotates while I make turns. How can I stop this? Select the North-up map orientation by voice, or by selecting “North-up”
from the
Map menu . See Map Orientation on page 62.
Sometimes, I cannot select between the North-up and
Heading-up map orientations. Why is this? The Heading-up map orientation can only be shown in the lower scales
(1/20 - 1 mile scales). See Map Scale on page 61.
While driving to my destination, the “time to go” display
sometimes increases, even though I am getting closer. The “Time to go” is based on actual road speeds. However if your speed
slows down when you encounter slower traffic, the system updates the
“Time to go” based of your actual speed to give you a better estimate of
arrival time.
