Answer I just got back from vw
Dear Alex,
Your VW came with the most recent map update available at the time you purchased the car and further updates put out by Navteq are not provided by VW and must be purchased either from your local VW dealer or NavTeq directly.
You can visit your local VW dealer to purchase the latest map updates for your Passat or you can purchase the map update from NavTeq directly on the following link: *

Thank you for taking the time to contact Volkswagen and if you have any other questions please feel free to contact our Customer CARE Center at 800-822-8987 from 8 a.m. to 6 p.m., in your local time zone.
