retaining M button programming without iDrive?
(unsurprisingly) the back of the car was pretty easy to strip out, and i'm moving to the front pretty soon. got me thinking -- if i rip out the idrive and don't put it back in, do i lose the ability to program the M button? or will it retain whatever setting it last took? right now it puts the car into S4, DSC Off, and Normal power mode.
if so, is the middle ground to rip out hte radio module but keep the screen? or is the radio module the brains of iDrive and the screen is just a scree?
