I just bought an '06 Vantage from a friend, never thought I would own such a fine machine but with only 28k miles and pristine condition I couldn't pass it up. I'm starting to acquaint myself with car and noticed the maps on the navigation system are out of date. It doesn't have some of the newer roads in town, which come up fine on my Garmin system in the Dodge. How do I go about getting updates and installing? Is this something that can only be done by the dealer? I wen't to NAVTEQ's website but they don't list Aston Martin
