Hi peeps, has anyone ever retrofitted an iDrive system from some of the newer BMWs (E70, etc) into the older models (E53, etc)...
I know there would be a lot involved, including major modifications to the dash, but....
Also some of the functionality may not all work...but someone may have done it.
So anyone know of someone doing this?
