ipod to kenwood cd changer

I have searched for a while and I still dont have a grasp on the ipod. I am looking for an inexpensive way to plug in the ipod into a kenwood cd changer port. I would prefer to be able to have the ipod charge, nad to be able to control it from the head unit, but both are not necessary. I just need to have good sound quility (no FM transmitter or cassete adapter). can anyone refer me to an adapter, or at least the how-to wire it manually?

PIE model KNW-AUX if you have a changer, PIE KNW/13-RCA if you do not.PIE phone # (818) 678-3690

thanx, but first of all its $80 (to expensive). secondly, when connected it doesnt let you use the ipod buttons. since my dispaly is very small it'll be a very big pain.
