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 or order a new SD memory stick online. 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.
