ok, so I just got the car, which I've wanted one for 10 yrs. bought the USA SPEC, plug ged it into the rear of the radio and........nothing. I have to assume this is not the right unit to use. Would some please shed some light on what one will actually work by plugging it into the SAT at the rear of the radio? PS-- I have already removed the stock amp and have my own installed (450 JL Audio amp mated to MB Quarts). Thank you in advance.

 

15 not 5

 

Here is the fix for all of those who have been waiting with bated breath. This comes right from USA SPEC. I did it and it works: ............

"The PA15INFI does not connect to the AMP, it connects to the “prewired sat cable” located next to the factory amp inside the car. If the amp is no longer, the “prewired sat cable” should be intact. All the installer had to do was, find the cable and connected the Harness from the PA15INFi into it, ran it to the from connected the PA15INFI into it and had the ipod cable come out of the glove box or center console in your car. If you want something that connects to the back of the radio, you will need the USA SPEC part number PA15NIS".

So there you go.
