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.

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.

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
