Any Europe DVD map for H2 navigation?

I have worked hell and back for this, and haven't found any other good answer than going for aftermarket Nav receiver, that has the maps included. However one very potential thread to follow is trying to find the GM Europe map for Corvette. Since GM is importing Corvettes to Europe and they offer Navigation radio as an option they must have the maps too. And what I know, the receiver is identical to the Hummer Nav radio.
