Can someone tell me the part number for hooking up a iPod Video to my AVIC Z2...? I noticed a CD-IB100II...is that the correct cable or adapter for the Z2 and iPod Video? thanks for you help

I noticed when I looked up CD-IB100II..it came up with just a cable and then a picture of a box-like device with a ipod cable. Which one works with the the AVIC Z2 unit? thanks
