Guidance, Routing
Problem Solution
The navi does not route me the same way I would go, or the
way some other mapping progr am displays. Why is this? The navigation system attempts to
generate the optimum route. See
Changing the Routing Method on page48.
Why is the street I’m on not s hown on the map? It has been
here for more than a year. 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 rear shelf) may be
blocked by personal items. For best re ception, remove items from the rear
shelf, such as radar detectors, cell phones, or loose articles.
 Metallic tinting or other after-marke t devices can interfere with the GPS
reception. Please see your dealer. Also see System Limitations on
page104.
I entered a destination, but th e blue highlighted route and
voice guidance stopped, or turned into a blue/purple dashed
line before I got to my destination. Why is this? Your route has entered
an unverified area. See Unverified Area Routing on
page88.
The map rotates while I make a turns, Ho w can I stop this? Select the “North-up” ma p orientation by voice, or by touching the map
orientation icon on the map screen. See Map Orientation on page57.
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 page56.
While driving to my destinati on, 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 spee d 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 syst
em is unaware of the width of the
intersecting road. Large differences is vehicle position can indicate a
temporary loss of the GPS signal. See GPS Reception Issues on page104.
