what kind of cable can i use i see 2 of them out their. one hooks up to the cd and the other has rc jacks .

You need either the Pioneer ipod cable or the apple composite ipod cable. Both of the cables are basically the same. They have a USB plug for charging and controlling the ipod, and RCA plugs to send the audio/video signal to the radio.
