Traffic Options
Read the following Options descriptions to understand
how the XM NavTraffic™ operates.
XM NavTraffic™ (USA and Canada)
The vehicle’s navigation system may have (if equipped)
an XM NavTraffic™ receiver. XM NavTraffic™ is a
subscription service provided via XM™ Satellite Radio.
XM NavTraffic™ provides real-time traffic information
fully integrated to the navigation system to display
current traffic conditions for a driver’s chosen route.
XM NavTraffic™ allows drivers to make the most
informed, timesaving routing decisions.
If the Traffic touch screen button is pressed or if
an attempt is made to turn on the traffic display in
the Navigation Setup Menu without a subscription,
a Caution screen displays indicating that XM traffic
is not activated.Three types of traffic information for major roadways are
displayed on the navigation system:
Unscheduled traffic incident data, such as accidents
and disabled vehicles
Scheduled traffic incident data, such as road
construction and road closures
Traffic ow information (rate of speed data)
Traffic information is delivered to the vehicle by the XM™
Radio satellites. XM NavTraffic™ makes it possible for
the navigation system to provide continuously updated
traffic information personalized for a driver’s needs.

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’s
website, 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 4-59on 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.
