Just wanted to hear some thoughts on this.
I have the factory radio head unit in my car, w/ cassette. My car had the factory slave CD unit in the console but I removed it. I am using a cassette adapter with hidden wire to run my XM, so I really can't use that wire jack for another audio source.
I've been looking at adding an aux input to use the wiring of the CD slave to run my iphone audio to. There's a product out there to fill this need ( PAC Audio AAI-GM9
) but it requires the use of a fully functioning slave unit. When I removed my CD player, I built a panel in the opening to mount a couple switches and my phone cradle on, so putting the CD back in isn't really an option.
It's been a while since I took my CD out, but IIRC when the player is activated, it overrides the radio until the "stop" button is pushed. It seems to me, looking at the FSM, that there ought to be a way to wire a switched circuit into the 9 pin harness that would make the radio head unit "think" there's a slave on the harness when there isn't. For example: flip a switch, powers up the override circuit on the radio and plays audio from the AAI module.
Does anyone have experience with the AAI-GM9? Is there a way to simulate a slave unit?
I only know enough about car audio to be dangerous,
so I apologize if I've got my head up my butt on this one.
