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 Maps on
page 2-4. Dispose of the old disc to avoid confusion
about which disc is the most current.
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 DVD is updated, more detail
may become available for areas which previously had
limited detail. See Ordering Map DVDs on page 2-42.
