Ordering Map DVDs
The map DVD in the vehicle is the most up-to-date
information available when the vehicle was produced.
The map DVD is updated periodically, provided that the
map information has changed.
For 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. For any updates or replacements, call
the GM Nav Disc Center or order a new disc online.
Have the Vehicle Identification Number (VIN) available
when ordering to ensure the correct and most
up-to-date DVD map disc for the vehicle is sent. See
“Vehicle Identification Number (VIN)” in the Index of the
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.
