Models: All 2008 models with factory-installed, in-vehicle navigation — either standard or optional (Cadillac CTS, SRX, STS, XLR, Escalade, Escalade EXT, Escalade ESV – Hummer H2 and H3 – Buick Lucerne and Enclave – Pontiac Grand Prix and Torrent – Saturn Outlook and Relay – GMC Sierra, Yukon, Yukon XL, Envoy, and Acadia – Chevy Silverado, Avalanche, Tahoe, Suburban, Trailblazer, Equinox, Uplander, and Corvette)
The program previously included two free DVD map updates for customers who purchased a GM vehicle with a factory navigation system, installed when the vehicle was built.
The program has been modified for the 2008 model year and beyond. Free DVD map updates are no longer included. This does not affect the original DVD map disc which is provided with the new vehicle. This also does not affect the owners of 2006 and 2007 model year vehicles with factory in-vehicle navigation. Those owners are still eligible to obtain a free update or updates.
DVD map updates will continue to be offered by the GM Nav Disc Center. The data on the DVD map disc ages at a rate of 15-20% per year. As the data ages, the functionality of the navigation system declines. The DVD map updates are available annually at the beginning of the new model year.
The GM Nav Disc Center can be contacted for both disc orders or for assistance with nav system operation. Order discs via the website, www.gmnavdisc.com, or by phone, 1-877-NAV-DISC (1-877-628-3472). Contact information for the Center is also included in the Navigation Owner’s Manual Supplement (in the glovebox) and on the face of the DVD disc included with the new vehicle.
