As Jochen said me to use Navcoder to recode mono to colour I needed a car which recognize the gps. The problem was that my car does not recognize the mk3. I had to find a car with mono monitor and place Navcoder on it. I was not this possibility. So I did it directly by recoding the V27 nav_sw software!!
For the changing of the language I will buy Ibus interface+Navcoder in the next days!
Thank you for the help!!
