Gentlemen,
I have used the great NavTweak tool to edit the NAVBOOT file in the 29.1 software for the MKIV to adapt to Danish language. For those requesting a full Danish version please download my NAVBOOT file at the location:
http://www.megaupload.com/dk/?d=WU1THHO8
Procedure:
1) Download above file to your PC and rename it to "navboot"
2) Download ver. 29.1 image for the MKIV (found elsewhere on X5W)
3) Open the 29.1 image using UltraISO (free software)
4) Go to directory V_2/RR/0101/BMWC01S/app_sw
5) Delete the original "navboot" file from the view
6) Insert the downloaded navboot file at the same spot
7) Burn revised image to CD using UltraISO
8) Bring the CD to your car and update (procedure found elsewhere on X5W)
9) Done! Now all your menus and navigation are in Danish (except for voice that remains in English) and you have stylish BMW logo as a start-up (=splash) screen.
