Oh wow - you sir are one pioneering SOB. Finally, proof-positive that it can be done. Too cool! BTW, you are now the only guy in the US (in all of North America?), with a pre 2011.5 car with iDrive, MDrive, but no EDC.
Now - as Julie said - the next hurdle (for the community, not for you
) is retrofitting the non-iDrive-dependent MDrive functionality found in many non-iDrive-equipped M3s (including all the ones sold in the US) from MY2011.5 onward. I suspect there are a lot more of us out there with no iDrive and no MDrive than there are with iDrive but no MDrive. The big question remains, were there hardware changes made to support this feature or not? Unlike in your situation, we have to rely on holding down the M Button to program and it is not clear whether our current steering wheel button can support that (though it seems such a minor detail on the surface). Even if we could not get the programming, though, I would be happy with all of my settings hardcoded (which would also inlude the two additional DCT settings that you do not have). Presumably the hardcoded settings could be determined and set as part of the coding (it was claimed this is possible with the M3 GTS).
So tell us, how does it feel to have this functionality now that you have been so accustomed to driving an M3 without it for all these years? Do you now immediately hit the M Button when you get in the car (which I assume you have left set to MDM, Sport, Sport as show in the pic)? Do you find Servotronic Sport much more suited to the car? What about Sport+ "Power" have you tried it?
And what about the button on the wheel? Have you considered or investigated getting one that says "M"? And were you able to choose which or the two "wildcard" buttons was to be transformed into the M Button?
