I bought the controller at the Japanese BMW dealer. I order the controller part numbered 048 but it came as 9189049.
I tried it but it didn't work 100%. all the buttons and functions worked except dial(scroll function) but the cross movement works.
Is it just my program old?
sorry I posted the same post on the related thread.
