steps listed here and still are experiencing problems,
see your dealer/retailer for assistance.
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, www.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
on page 2-4
. Dispose of the old disc to avoid confusion
about which disc is the most current.
Database Coverage Explanations
Map detail varies. Some areas have greater map detail
than others. The navigation system will only work
as well as the information provided by the map disc.
