MP3Car.com - View Single Post - FAQ: Hacking Your Steering Wheel Buttons to Control Your PC

Does your Commodore use a single wire which transmits variable levels of resistance?

I forget what it's called, but in my car each button has it's own resistance value and the headunit translates it. The PAC Steering Wheel control SWI-2 and SWI-X does the same thing and then translates that to a IR signal.

I know some of the latest cars use a digital signal over a single wire.
