If the System Needs
Service
If the navigation system needs
service and the steps listed here
have been followed but there are still
problems, see your dealer/retailer
for assistance.
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,
www.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 38. Dispose of the old disc
to avoid confusion about which
disc is the most current.
Database Coverage
Explanations
Coverage area depends upon the
map detail available. Some areas
have greater map detail than others.
The navigation system works only as
well as the information provided on
the map disc. See Ordering Map
DVDs on page 72 on how to obtain
updated map information.
Voice Recognition
The navigation system’s voice
recognition allows for hands-free
operation of navigation and audio
system features. Voice recognition
can be used when the ignition is on
or in ACC/ACCESSORY or when
Retained Accessory Power (RAP)
is active.
The radio commands feature only
works if the map DVD is inserted.
Bluetooth
®

functions
will work without the map DVD
inserted. See Bluetooth
®

in the index of the vehicle’s
owner manual.
