I was playing around with this some more and BMW have already included a alternative Colour Set within the existing navboot. Perhaps this one was used in a prior release of the firmware prior to my knowledge. Its actually a bit similar to the green one I made above .... perhaps a bit lighter and easier on the eyes. I am sure they had a whole group of folks working on the most optimum colours !

In any case, you can find it in "colours for widescreen" rom_col_8 or rom_col_9. I copied this over to rom_col_ 1 to replace the blue split screen colour set ...

Navtweak is a great program !!! :-)
