Touch Output: USB to AV?

[zero157h7]

I was wondering if anyone has any idea if you can use usb to av cables to output video and/or audio.

I ask because I have a DVD player in my truck that has an input section and I would like to be able to play mp3s on it with a direct line. I do not want to bother buying a cable and plugging it in the unit if it will not work.
