Navigation Manual

After verifying your address you should receive the
updated disc in about two weeks. 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 18. Dispose of the old disc to avoid
confusion about which disc is the most current.
If you have any questions about the operation
of the navigation system or the update process,
call the GM Nav Disc Center or go to the center’s
website. If you need any future 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.
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 53.
