I just picked up a Passat Wagaon with SatNav fitted by the dealer. Looking at the toc file in the root of the DVD I can see the Navigation DVD was based upon Q1 2008 Sensis information. Can people let me know if this is the latest Volkswagen has got or whether i should pushing my dealer to give a more up-to-date version?

Are people getting Version 3 or 4 DVD's?

My DVD is called Volkswagen Navigation CY (V2)
CD Label 6613
Date Feb.10.2008

In 3 or 5 years time how do i get updated information? Do i download updates from Sensis and merge or do i have to buy a new DVD from the Dealer @ $1050 a pop?
