Nav System Disks
Posted: Wed Apr 05, 2006 10:51 pm
GM will no longer supply the Nav Disks through the Parts System. The dealer now has to call an 800 # or go to (yet another) website to order the disks. All 2006 and later get 2 free annual updates. If you don't get your postcard to verify your mailing address, you can call 877-NAV-DISC (1-877-628-3472). The Website is http://www.gmnavdisc.com. Certified Used/Pre-Owned customers are eligable for 1 free update disc. Hope this helps you NAV people!
