Does anyone know if my car(55 plate mk1 leon cupra r 225) uses 'Can bus' or if uses the ignition feed to work the radio? I have tried the Aura 2 radio and it works but doesn't remember the radio code or stations you set etc. I'm not sure if I've bought the wrong radio or not. Any help would be greatly appreciated. The pioneer aftermarket cd player that came with the car works fine, no problems at all with it.
