No, my May 07 335i E92 has the one button controller but does have voice command. Only access button for that is on the steering wheel.
I want to swap this out for the multi-button controller. will an 09 controller and center console trim piece do the trick? I've heard stories that it's plug n play. I've had the HPFP recall work which includes system reprogramming...
