I'm thinking about the possibility of fitting a multifunction steering wheel to a 500 with an ordinary wheel. My question is: are the wiring looms the same with sections unused or does this have a separate loom. I'm assuming this connects to either the interior CAN or to a MOST system controling the audio. If I'm using an aftermarket android head unit can I effectively create a unique CAN (MOST) network to link the items. At the moment I'm at the limit of my current knowledge therefore any help would be appreciated.
