Frequently Asked Questions

Guidance, Routing
Problem Solution
The navigation system 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 traffi c
problems. How do I stop these pop-up messages? This feature can be turned off. See Traffi c Rerouting on page 109 .
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 129 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 back of the navigation display) may
be blocked by personal items. For best reception, remove items from the
dashboard, 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 124 .
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 unverifi ed area. See Unverifi ed Area Routing on
page 102 .
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 traffi c, the system updates the “Time
to go” based of your actual speed to give you a better estimate of arrival time.
The vehicle position icon on the map “lags” a short
distance behind, especially when I arrive at an
intersection. Is there anything wrong? No. When at an intersection, the system is unaware of the width of the
intersecting road. Large differences in vehicle position can indicate a
temporary loss of the GPS signal. See GPS Reception Issues on page 124 .
