You need the new Ver.31 OS disk. I don't know about the language. Read the pdf of Ver.31 which is posted on this board a few days ago. If you have trouble contact Edwin on bimmerboard.com nav forum or e38 forum. Edwin is located in the NL too and knows all this stuff. I don't have his phone number though.

I have now V31 installed, and it works great, Dutch is in it.

now i go tweak it with Navtweak.
