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.
