Check with Roz, I'm in the process of getting one from him, but the KCA410C, and or the KCA420C are the parts to integrate the iPod to your Alpine system. Since I have XM, and a CD changer, I would need both if I wanted to have control at the head unit for the iPod, or use just the 410 and be able to hook up the iPod and control it just from the iPod itself. I am going with just the 410, and mounting the iPod at the helm, and controlling it from there.
