Hi!
If you send it to Germany, they can code it
The price for the coding from 4:3 to 16:9, plus
TV Free funktion is 149 euro (about 200 USD)

And a little cheaper without the TV Free function.

I have listed all of the video module P/Ns on the Nav Forum on bimmerboard.com Look for posts numbered 230,716 and 523,380. There are some additional numbers from those in the post above.
