Ordering Map DVDs
The map DVD in the vehicle is the most up-to-date
information available when the vehicle was produced.
The map DVD is updated periodically, provided that the
map information has changed.
If there are 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, www.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. SeeVehicle Identification Number (VIN) on
page 6-81for 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 4-38. 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 4-52on 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.
The vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be played
even after the ignition is turned off. SeeRetained
Accessory Power (RAP) on page 2-25for more
information.
The audio system is operated using navigation system
menus. The audio menus are explained in this section.
