Just bought a 2009 Suburban LTZ with navigation and I was wondering if I needed to update the maps in the navigation system. And if I do, how is that done?

 

You can order the latest DVD from the GM site listed in the owner's manual for $200 or get one on eBay for less than $100.

 

Hey 09LTZBurb! For your reference, the GM NAV Disc Center can be reached at 1-877-NAV-DISC (1-877-628-3472) or go to the center's website, General Motors Navigation Center - Home. Feel free to let us know if there's anything we can look into for you.
