Global Positioning System (GPS)
The navigation system determines the position of the
vehicle by using satellite signals, various vehicle signals,
and map data.
At times, other interferences such as the satellite
condition, road con guration, the condition of the vehicle
and/or other circumstances can interfere with the
navigation system’s ability to determine the accurate
position of the vehicle.
The GPS shows the current position of the vehicle using
signals sent by the GPS Satellites of the United States
Department of Defense. When the vehicle is not
receiving signals from the satellites, a symbol appears
on the map screen. Refer toSymbols on page 4-16.
This system may not be available or interferences may
occur if any of the following are true:
Signals are obstructed by tall buildings, trees, large
trucks, or a tunnel.
Objects are located on the front dash of the vehicle.
Satellites are being repaired or improved.
After-market glass tinting has been applied to the
vehicle’s windshield.Notice:Do not apply after-market glass tinting to
the vehicle’s windows. Glass tinting interferes
with the system’s ability to receive GPS signals and
causes the system to malfunction. The window
might have to be replaced to correct the problem.
This would not be covered by the warranty.
For more information if the GPS is not functioning
properly, seeIf the System Needs Service on page 4-56
andProblems with Route Guidance on page 4-55.
Vehicle Positioning
At times, the position of the vehicle on the map may
be inaccurate due to one or more of the following
reasons:
Road system has changed.
Vehicle is driving on slippery road surfaces such as
in sand, gravel, and/or snow.
Vehicle is traveling on winding roads.
Vehicle is on a long straight road.
Vehicle is approaching a tall building or a large
vehicle.
Surface streets run parallel to a freeway.
Vehicle has just been transferred by a vehicle
carrier or a ferry.

Some routes may not be searched.
The route to the destination may not be shown if
there are new roads, if roads have recently
changed, or if certain roads are not listed on the
map DVD. SeeOrdering Map DVDs on page 4-56.
To recalibrate the vehicle’s position on the map, see
your dealer/retailer.
If the System Needs Service
If your system needs service and you have followed the
steps listed here and still are experiencing problems,
see your dealer/retailer for assistance.
Ordering Map DVDs
The map DVD in your vehicle is the most up-to-date
information available when your vehicle was produced.
The map DVD is updated periodically, provided that
the map information has changed.
If you have any questions about the operation of the
navigation system or the update process, contact
the GM Nav Disc Center toll-free phone number,
1-877-NAV-DISC (1-877-628-3472) or go to the center’swebsite, gmnavdisc.com. If you need any updates or a
replacement disc, because the current disc is lost,
damaged, or needs to be updated, call the GM Nav Disc
Center or order a new disc online. To order a disc,
have your Vehicle Identi cation Number (VIN) available.
This helps the center make sure you receive the
correct and most up-to-date DVD map disc for your
vehicle. See “Vehicle Identi cation Number (VIN)” in the
Index of your vehicle’s owner manual for more
information.
After receiving the updated disc, replace the old disc in
the navigation system. See “Installing the DVD Map
Disc” and “Ejecting the DVD Map Disc” underMaps on
page 4-14. Dispose of the old disc to avoid confusion
about which disc is the most current.Database Coverage Explanations
Coverage area depends upon the map detail available.
Some areas have greater map detail than others.
The navigation system works only as well as the
information provided on the map disc. SeeOrdering
Map DVDs on page 4-56on how to obtain updated map
information.

Navigation Audio System
Notice:Before adding any sound equipment to the
vehicle, such as an audio system, CD player, CB
radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer/retailer. Also, check federal rules covering
mobile radio and telephone units. If sound
equipment can be added, it is very important to do
it properly. Added sound equipment can interfere
with the operation of the vehicle’s engine, radio, or
other systems, and even damage them. The
vehicle’s systems can interfere with the operation of
sound equipment that has been added.
Notice:The chime signals related to safety belts,
parking brake, and other functions of the vehicle
operate through the navigation system. If that
equipment is replaced or additional equipment is
added to the vehicle, the chimes may not work.
Make sure that replacement or additional equipment
is compatible with the vehicle before installing it.
See “Accessories and Modi cations” in the Index of
the vehicle’s owner manual.
