Wow!!! That's simply amazing. Thank you very much especially to Jochen for the expert advice and the rest of the members that have contributed. I hope this coding will solve my troubles, as the dealer could not help in this matter. So, I guess I'll have to order the i-bus interface and register Navcoder to do the trick. By the way, what would I benefit for encoding the navi system to the car with the BMW dealer's GT-1 after I code the mk4 from mono to color?

I'll be back in a couple of weeks until I receive the I-bus interface and post back the news....

@ KiwiJochen: The GR stands for Greece by the way - Thank you very much for offering to visit you.
