I've currently got an avic D3 and the cd-i200 cable, along with my 4th generation ipod nano. I am thus able to get the ipod music to work, but not the video.

I've got hold of some wires for the back of the D3 that allow me to attach a composite AV cable with the red, wite and yellow heads. obviously this will allow me to play the video from the ipod... but I was just wondering whether this cable would also allow me to play my music from the ipod and have the ipod interface on the d3... allowing me to remove the cd-i200 cable and simply have the one composite av cable? or will i still need the 2?

thanks in advance

You need the Pioneer cable to control the ipod from the D3. So you need the 2 cables to do what you want.
