Tell them you don't want the navigation if it is not a complete system as you expected.

Then find a good dealer to install the correct version.

If that does not work, just drive the car into the dealer's salesfloor and hand the key to a lot lizard telling them you don't want to put up with their crud anymore.

Man, I am glad I worked with a good dealer.

I think my us version navigation book is in french and english.
