102Navigation System
System Limitations
Although your navigation system is one
of the most highly sophisticated pieces
of equipment you will find in a modern
automobile, you may find during its use
that it has certain limitations.
The system uses signals from the Global
Positioning System (GPS) to aid in
determining its current location. The
GPS is operated by the U.S.
Department of Defense. For security
reasons, there are certain inaccuracies
built into the GPS that the navigation
system must constantly compensate for.
This can cause occasional positioning
errors of up to several hundred feet.
For example, in urban areas where
streets are close together, this could
cause the system to show that you are
traveling on a street that parallels the
street you are actually on. The system
will, under most circumstances, correct
itself while you drive. Depending on your current view of the
sky and the position of the satellites, the
elevation may be shown incorrectly.
You may also notice some delay of the
vehicle position icon at intersections;
this is normal.
GPS Reception Issues
The signals received from the GPS
satellites are extremely weak (less than
a millionth of the strength of a local FM
station) and requir
e an unobstructed
view of the sky. The signal can easily be
interrupted or interfered with by the
following:
 Aftermarket metallic window tint above or to the sides of the GPS
antenna (located under the
dashboard)
 Cell phones, PDAs, or other electronic devices docked in a cradle
or lying loose on the dashboard
 Radar detectors mounted on the dashboard
 Remote starters, or “hidden” vehicle tracking systems mounted near the
navigation unit  Other aftermarket audio electronic
devices mounted near the navigation
unit
 Trees, tall buildings, freeway overpasses, tunnels, or overhead
electrical power wires
Although the system will direct you to
your desired destination, it may not
always generate what you consider to be
the most direct rout e. Try changing the
method of routing. See Changing the
Routing Method on page47. You may
also have Unverified Area Routing set
to OFF. See Unverified Area Routing on
page86.
Additionally, the mapping database
contains verified and unverified maps.
See Map Overview on page6. A
Disclaimer screen will warn you if your
route includes unverified streets.
Unverified streets may be missing from
the map, in the wrong location, or have
an incorrect name or address range.
Exercise addition al caution when
driving in these unverified areas.

122Navigation System
Operation in Alaska and
Hawaii
Certain functions that rely on a satellite
signal will not work correctly in Alaska
and Hawaii. These functions include but
are not limited to XM radio, automatic
clock updates, and time zone
adjustments.
Alaska
If the vehicle was purchased in the
lower 48 states and driven to Alaska, the
system cannot display maps. The
message “Vehicle is out of the
database...” will be displayed.
Hawaii
This section describes the differences in
navigation system operation for vehicles
delivered in Hawaii.
XM Radio
Navigation-equipped vehicles delivered
to Hawaii are equipped with XM
hardware, but XM broadcasting is not
available; therefore sections of the
manual that mention XM audio do not
apply. Vehicles originally delivered to
the U.S. mainland and shipped to Hawaii
also have XM, but will not function
because the XM satellites (aimed toward
the U.S. mainland) are too far away to
obtain reception.
Map Coverage
All roads displayed on the Hawaii map
screens are detailed coverage roads.
Text related to “unverified” roads or
areas are not applicable. The following
topics do not apply in Hawaii:
 Unverified road descriptions (see page
6 and 86 ).
 Cautions and pop-up windows related to unverified roads (see page
63).  Setup entries that relate to turning on
or off unverified routing (see
page 87 ).
 When zooming in and out, there is no 350-mile scale for Hawaii.
Other Map Issues
 See the coverage section for a list of islands with coverage (see page 109).
 Freeway Exit information does not
exist in Hawaii, so the “Freeway Exit
Info” icon is not shown on the icon
bar.

Navigation System131
Troubleshooting
Screen Error Message Solution
Navigation system is unable to acquire a proper GPS signal.
Make sure there is nothing on the dashboard blocking the GPS antenna
(aftermarket metallic window tinting or aftermarket devices placed on the
dashboard, like radar detectors, cell p hones, or loose items). If the dashboard
is clear of objects, move the vehicle to an open space away from tall buildings,
trees, etc.

Navigation unit door is open or No DVD disc is inserted.
Please check system. Make sure that the navigation DVD disc
is inserted with the label side up
and the navigation unit door is fully snapped closed (see page108).
No DVD disc. Please check system. Check that the navigation DVD disc is in serted with the label side up (see
page108). If the problem persists, see your dealer.
DVD disc reading error (unfor matted). Please consult your
dealer. Check the DVD disc surface
for deep scratches or other damage. Make sure
you are using a navigation DVD (white-c olored label). The system cannot
read other mapping databases or vide o DVDs. If the problem persists, see
your dealer.
Display temp is too high. Syst em 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 temperature 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 system has difficulty
reading the DVD. The system will st art up when the temperature warms up.
Navigation system voice recognition ca nnot be activated
when another unit is us ing the audio system. HandsFreeLink (HFL) can override the
navigation system. Make sure the
HFL TALK button is not on when you press the NAVI TALK button, or the
message will appear. Simply press the HFL BACK button to resume
control of the navigation voice buttons.

Glossary
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.
MW - Maneuver Window. While en
route to a destination, this window
displays informatio n about the next
maneuver.

system.
North Pointer - The map symbol showing the map orientation. See
page56. Off Route -
This occurs when the user
leaves mapped roads. Off-road
tracking dots (“breadcrumbs”) are
displayed if the option is enabled in
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.”
Outlying Areas - These are rural areas
that typically have only their main
roads mapped. All other roads are
shown in light brown for reference
only, since they have not been
verified.
PIN - Personal Identification Number.
A 4-digit number created by the
customer to protect personal
information.
POI - Point of Interest. These are the
businesses, schools, etc. found under
the Places option on the Enter
destination by screen. See page32. Polygon - Colored areas on the
map
screen denoting parks, schools, etc.
See Map Screen Legend “Map
Features” for a list of the assigned
colors. See page51.
QWERTY - Keyboard layout
resembling the typewriter keys. The
