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 Identification 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 Identification 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” under Maps on
page 4-14. Dispose of the old disc to avoid confusion
about which disc is the most current.

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. See Ordering
Map DVDs on page 4-56 on how to obtain updated map
