I installed it myself, its not hard at all. With PCM, my choice place would be somewhere like the front of the ashtray door.

The spoiler removal was very easy, just a few hex screws and it comes right off.

 

I have an 04 S with PCM; I had a professional installer do the work. He put the Kenwood Sirius tuner faceplate in the sunglasses holder, as others have done.

But I had him use an fm modulator because I understood you could not plug anything into the back of the PCM.

Thats correct, what he did is what I did for the iPod using an FM Modulator. I am not sure about the sunglass holder as I am always sitting on sunglasses and use it :-)
