Frequently Asked Questions
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 page51.
Why is the street I’m on not s hown on the map? It has been
here for more than a year. The mapping database is
constantly undergoing revision. See page129 for
ways to obtain the latest de tailed 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
rear window beneath the rear shelf)
may be blocked by personal items. For best reception, remove items from
the rear shelf, such as radar det ectors, 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
page112.
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
page93.
The map rotates while I make a 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 page61.
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 page60.
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 page112.

Troubleshooting
* If the error persists, or is shown for a wide area, see your dealer.
Screen Error Message Solution
Navigation system is unabl e to acquire a proper GPS
signal. Make sure there is nothing on the rear
shelf blocking the GPS antenna (after-
market metallic window tinti ng or after-market devices placed on the rear shelf like
radar detectors, cell phones, or loose items) . If the rear shelf is clear of objects,
move the vehicle to an open space away from tall buildings, trees, etc.
Navigation unit door is ope n or No DVD disc is
inserted. Please check system. Make sure that the navigati
on DVD disc is inserted with the label side up and the
navigation unit door is fully snapped closed (see page118).
No DVD disc. Please check syst em. Check that the navigation DVD disc is inserted with the label side up (page118). If
the problem persists, see your dealer.
DVD disc reading error (unf ormatted). Please consult
your dealer. Check the DVD disc surface for deep scra
tches or other damage. Make sure you are
using a Navigation DVD (white colored la bel). The system cannot read other
mapping databases or video DVDs. If the problem persists, see your dealer.
Display temp is too high. Sy stem will shut down until
display cools down. This message will appear briefly when the
display temperature is too high, and then
the display will turn off until the temper ature cools down. The system will turn
back on when the display cools down.
Outside temperature is low. System will take awhile to
start up. The temperature is below -22°F and the
navigation ECU has difficulty reading the
DVD. The system will start up when the temperature warms up.
Route has not been completed. Please try again from a
different location. This message will appear when you are routi
ng to or from a place (new area) that is
not in the database. Try planning a different route to or from a different location.*
No alternate route found. Original route will be
followed. No alternative route method was found. The
original route method will be used.*
Ensure that a road name is displayed at the bottom of the map.
This destination cannot be found in databa se. The destination was not found in the data base. Try another destination nearby, or
select the destination with the Interface Dial.*

disconnected. This can take 10 to 45
minutes with the ve hicle out in an
open area.
Instant Fuel - The current
instantaneous fuel economy value as
displayed by the Trip computer
screen.
LCD - Liquid Crystal Display. The
navigation screen.
Map Matching - The received GPS
information allows the navigation
system to position the vehicle on the
map. Map matching has occurred if
the map screen is displaying the
current street name in the bottom-
shaded area.
Mic - Abbreviation for the microphone
used for receiving voice commands.
It is located near the map light in the
ceiling.
Multi-Information Display (MID) -

displays information about the next
maneuver.
Navi - Abbreviation for the navigation
system.
North Pointer - The map symbol
showing the map orientation. See
page61.
Off Route - This occurs when the user
leaves mapped roads. Off road
tracking dots (“breadcrumbs”) are

the Setup screen. The user can use
them to return to a mapped road. The
bottom of the navigation screen will
say “Not on a digitized road.”
