Ordering Map DVDs
The map data in your vehicle is the most up-to-date
information available when your 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, www.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 will
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 2-45.
