I tried to install an ipod adapter unit to my 2004 S2000 factory head unit. I used a PAC AAI-HON iPOD Aux Input 2003-2006 S2000. It won't switch to aux, it just goes from the CD to the radio and vise versa. I'm not sure if it's my head unit or the adapter that is faulty... or maybe there is a problem with these PAC converters or did i hook it up wrong? It was kinda hard to find and now that i found it and installed it, it doesn't work!

I plugged in the 14 pin connector, i disconnected the white loop and connected the brown loop, grounded the grey wire(aux2 negative ground trigger) and left the orange wire(aux2 positive trigger) unplugged just like the directions said to do. I would think it needs power but the directions say not to hook up the positive trigger for the ipod application. Doesn't seem right to me... i'm hoping there is someone out there that has some experience with this same adapter.
