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 for
assistance.
Map Data Updates
The map data in the vehicle is the
most up-to-date information
available when the vehicle was
produced. The map data is updated
periodically, provided that the map
information has changed.
For 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 updates are
needed, call the GM Nav Disc
Center. To order map data, have the
vehicle's Vehicle Identification
Number (VIN) available. See
Vehicle Identification Number
(VIN) in the owner manual.
After receiving the updated map
data, see Maps 0 47.
Database Coverage
Explanations
Coverage areas vary with respect to
the level of map detail available for
any given area. Some areas feature
greater levels of detail than others.
If this happens, it does not mean
there is a problem with the system.
As the map data is updated, more
detail can become available for
areas that previously had limited
detail. See Map Data Updates 0 60.
