To recalibrate the vehicle’s position on the map, see

If the System Needs Service
If the navigation system needs service and the steps
listed here have been followed but there are still
problems, see your dealer/retailer for assistance.
Ordering Map DVDs
The map data in the vehicle is the most up-to-date
information available when the vehicle was produced.
The map data 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,
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, see “Installing the DVD
Map Disc” and “Ejecting the DVD Map Disc” under
Maps on page 2-5.
Database Coverage Explanations
Coverage areas vary with respect to the level of map
detail available for any given area. Some areas feature
greater levels of detail than others. If this happens, it
does not mean there is a problem with the system.
As the map data is updated, more detail may become
available for areas which previously had limited
detail. See Ordering Map DVDs on page 2-39.
