From website where I purchased converter: "Sony head units must have a joystick port referred to as RM-X2S or RM-X4S and it is actually a 3,5mm Stereo head phone type socket. Only UK Spec Head units will work with our interfaces. "

Would UK spec headunits matter since I should be getting all raw codes. I guess I'll need to find more on UK Saab steering wheel specs.
