If the System Needs
Service
If your system needs service and
you have followed the steps listed

Ordering Map DVDs
The map DVD in the vehicle is the
most up-to-date information
available when your vehicle was
produced. The map DVD 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. To update or
replace a disc, call the GM Nav Disc
Center or order a new disc online.
Have the Vehicle Identification
Number (VIN) available when
ordering. This ensures that 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.
