Just took delivery of a 2008 ML 320 CDI that has the factory head unit including back-up camera, sattelite radio, AM/FM, Navigation, CD and the otional 6 Disc CD Changer. My question is this... Can I add the iPod integration to this or is the 6 Disc CD Changer port needed for all iPod integration kits? I have installed iPod integration kits in several other vehicles I have owned, but this is the first Mercedes I have owned, so I am looking to others for advice. Any and all help is appriciated.
