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, 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 4-15. 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 4-61 on how to obtain updated map information.
Navigation Audio System
Notice: Before adding any sound equipment to
the vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer/retailer. Also, check federal rules covering
mobile radio and telephone units. If sound equipment
can be added, it is very important to do it properly.
Added sound equipment can interfere with the
operation of the vehicle’s engine, radio, or other
systems, and even damage them. The vehicle’s
systems can interfere with the operation of sound
equipment that has been added.
Notice: The chime signals related to safety belts,
parking brake, and other functions of the vehicle
operate through the navigation system. If that
equipment is replaced or additional equipment is
added to the vehicle, the chimes may not work.
Make sure that replacement or additional equipment
is compatible with the vehicle before installing it.
See “Accessories and Modifications” in the Index
of the vehicle’s owner manual.
