check  out the link above.
does anyone think its possible to set up a phatbox in this application?

If anyone can tell me how to test the other parts of the controls, I would realy apreciate it.

You could set up one using the kenwood FM modulator since it comes with a display and controls to hook up.. then use that aux setup to connect the CD changer audio to the keg / phatbox's RCA outs.

So far that is the plan, This should get me past the dreaded fequency loss of an FM modulator.
I have requested a wireing diagram from the12volt.com for this car. If I can figure out the way the factory changer is controlled, maybe an interface can be created. I know many people that would be intrested.
