its not difficult to change. and no im not working at bmw. im only a customer.
you have to change the existing tcu und mulf, put the 18 pins in a new connector and thats is.
only the can bus (Ecell needs it) is the problem at the moment. i took it from pdc, not working. ecell (telematik) is "speeking" abouve the can bus. media about the most.
i will now try another constaltion, i keep you informed when i solved the problem.
the difficult thing i to find an engineer who makes the coding on you location. no bmw dealer can do.
last week i recived the "media" snapin for the iphone4.
kind regards steven
