Look in the centre console. If you have 3 RCA input jacks [red, white, yellow] for [audio-R, audio-L, video], then you can plug in any MP3 player usng an adapter from the mini-stereo of the headphone output jack on the player, to the RCA connectors. You can sometimes get these adapter cables at the dollar store.

To play from the source plugged into the RCA jacks, select the device named AUX. (see p4-68 of manual)

You can even watch videos this way as long as the vehicle is stopped and the parking brake is set.
