Check it out, a member contacted me and ask me if this was possible. I have already tested the knob out and yes it works on pre LCI. Each button works perfectly. So I decided to go ahead and got the pieces together. Of course the LCI is so new that the trim was not available. To my surprise the control unit itself was available. So i ordered the knob and custom fitted the knob onto the trim. I went and got the closest matching leather to the M3 uses to wrap the trim. Install will follow as soon as I get that member to my place.
sorry for the blury pics.
