iPod Classic Audio & Video to TV

[Gala]

I have had an audio aux cable for a while and was able to play any audio from my iPod Video to any speaker or my car speakers. I have a mini TV in my car for my son and right now I plug that aux cable in to the iPod and the TV and all I get is audio. Can someone direct me/inform me of a cord that transfers both the video and the audio.

The little TV works like this; I have 2 screens, one is a DVD player and screen that has a yellow AV cord that runs from it to the other single screen. The single screen only has a yellow AV input and the DVD screen has the AV output. When they are connected they both have audio and video. I would love to be able to get the audio and video of my iPod on to either of these screens.
