The other day when I was at chop-chop shop, I saw an e39 a multifunctional steering (only the panel not the steering wheel itself). Made a quick check & was advised that multifunctionl steering cannot be used for non-multifunctional steering UDM. The reason was given that one should not mess-up with the wiring of UDM. Is it true?I really like to install the panel to my UDM. The UDM I'm driving is E39-528i has no built-in multifunctional steering. What can we do?
