Check the sticky "master mp3/wiring thread" at the top of this forum section. There are several PIE options available depending on what type of controls you want. Also, they are supposed to be connected at the CD changer end not behind the headunit so you should not be losing your displays. I opted for the X3 because I wanted to interface my MP3 player and my Sirus radio.
