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, 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 6-89for 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 4-39. Dispose of the old disc to avoid confusion
about which disc is the most current.
Database Coverage Explanations
Coverage areas vary with respect to the level of map
detail available for any given area. Some areas will
feature greater levels of detail than others. If this
happens, it does not mean there is a problem with the
system. As the map DVD is updated, more detail
may become available for areas which previously had
limited detail. SeeOrdering Map DVDs on page 4-53.

Navigation Audio System
Notice:Before adding any sound equipment to
your 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 your vehicle’s engine, radio,
or other systems, and even damage them.
Your vehicle’s systems can interfere with the
operation of sound equipment that has been added.
Your 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
