Would it connect via standard harness wires like that?
Yeah, the optical is likely how the changer is hooked up. I have one in my car, but I've never looked to see how it all works yet. There has to be a way for my devices to plug into the system though. Not sure where they hook up. Cause my head unit can also handle the phone option without upgrading to the full comand nav system.
