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 46.
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 104 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 under the center of the dashboard) ma
y be
blocked by personal items. For best
reception, remove
items from the
dashboard, such as radar detector
s, cell phones, or loose articles.
• Metallic tinting or other aftermarke
t devices can interfere with the GPS
reception. Please see your dealer. Also see
System Limitations
on page 99.
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 84.
The map rotates while I make turns. How can I stop this? Select
the North-up map orientation by voice, or by touching the map
orientation icon on the
map
screen. See Map Orientation
on page 55.
Sometimes, I cannot select between the North-up and
Heading-up map orientations. Why is this?
The Heading-up map orientation can onl
y be shown in the lower scales
(1/20 - 1 mile scales). See
Map Scale
on page 54.
While driving to my destination, the “time to go” display
sometimes increases, even th
ough 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 on your actual speed to give you a better estimate of
arrival time.
The vehicle position icon on th
e map “lags” a short distance
behind, especially when I arrive
at an intersection. Is there
anything wrong?
No. When at an in
tersection, the system is un
aware 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 99.
