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,

This helps the center make sure you receive the
correct and most up-to-date DVD map disc for your

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

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
