Have a search on Google for a guy called Rusty. Have had several discs off him for different cars and always work superbly. My neighbour got one for his D3 and works perfectly in UK and Europe.

Navteq sell the 2012 version on their website, but there are clever people out there who have worked out that Land Rover still use Navteq in their cars and the latest maps for those, be they USB or HDD updates use the same basic core.
Therefore it is possible to port the latest maps to a DVD format for use in our antiquated Denso D3 systems!
Is there an argument that if Land Rover/Navteq won't offer an update then a another can? Can it really be called a pirate copy when there hasn't been an original DVD to copy from?
Google and Apple have rather opened the can of worms when it comes to maps.
