Thanks to the work of Kiwijochen:thu mbup: and X5world I now have a color MK4!!
The unit was from an E46. (did not know this when I got it)

Used Navcoder and send Jochen the file to check what OS I had.
It was 4/1-60 so that was good.

We did a test NOT to downgrade but just put in the modded V29.
AND it worked like a charm!!!

I now have a working nav! and also used Navcoder to update car details and Dutch (for me ;-))

Thanks all for help and support!



Keep up the good work all!
