    RedSox123, you would have to install automotive auxiliary input adapter. An automotive auxiliary input adapter will allow you to input any mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo. Here is the adapter you will need:
