Navigation System
System LimitationsAlthough 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 GPS signals 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 tens of metres.
For example, in urban areas where
streets are close together, this could
cause the system to show that you are
travelling 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 IssuesThe signals received from the GPS
satellites are extremely weak (less than
a millionth of the strength of a local FM
station) and require an unobstructed
view of 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, highway
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 route. Try changing the
method of routing. See Changing the
Routing Method on page 46. You may
also have Unverified Area Routing set
to OFF. See Unverified Area Routing on
page 83.
Additionally, the mapping database
contains verified and unverified maps.
See Map Overview on page 6. 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 additional caution when
driving in these unverified areas.

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 phones, 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 page 104).
No DVD disc. Please check system. Check that the navigation DVD disc is inserted with the label side up (see
page 104). If the problem persists, see your dealer.
DVD disc reading error (unformatted). Please consult your
dealer.Check the DVD disc surface for deep scratches or other damage. Make sure
you are using a navigation DVD (turquoise-coloured [blue/green] label).
The system cannot read other mapping databases or video DVDs. If the
problem persists, see your dealer.
Display temp is too high. System 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 a while to start up. The temperature is below -30°C and the navigation system has difficulty
reading the DVD. The system will start up when the temperature warms up.
Navigation system voice recognition cannot be activated when
another unit is using the audio system.Bluetooth® HandsFreeLink® 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.
MP3 - A music file format that can be
played from a CD-R, USB thumb
drive, or PC card.
MW - Manoeuvre Window. While en
route to a destination, this window
displays information about the next
manoeuvre.
Navi - Abbreviation for the navigation
system.
North Pointer - The map symbol
showing the map orientation (see
page 55).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.
PC Card - An adaptor card (sometimes
called a PCMCIA card) that can
contain a compact flash, or SD media
clip with MP3 or WMA music files.
PIN - Personal Identification Number.
A 4-digit number created by the client
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 page 31.Polygon - Coloured areas on the map
screen denoting parks, schools, etc.
See Map Screen Legend “Map
Features” for a list of the assigned
colours. See page 50.
QWERTY - Keyboard layout

audio unit. See Entering the Security
Code on page 96.
Touch Sensor - The touch sensor on the

GlossaryUnverified Streets - These streets have
not been verified for turn restrictions,
one-way, etc. They are shown in light
brown on the map. Unverified streets
may be missing from the map, shown
in the wrong location, or have an

USB - Universal Serial Bus. A computer
hardware interface used to store and
play audio files (MP3, WMA, AAC)
from USB devices, such as thumb
drives or iPods. See the Audio section
