2005 pontiac sunfire stereo

I am wanting to have a cable coming from the stereo that I can hook into the headphone jack of my mp3 player. I took the stereo out to see if it had RCA female jacks on the back of it, but it did not. I did see a port with a bunch of pins in it, but I do not know what this is for. Is there a way that I can use the empty port to hook up my mp3 player? i.e. Is there a cable made that will hook into the empty port that has rca jacks on the end of it so I can use a cable to run to my mp3 player?

does your deck have changer control or an aux button on the front. If it does you can use a peripheral AUX BOX and use your mp3 player that way. What you are describing sounds like the correct hook updouble-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

Yeah the same button that changes from radio to CD is also an aux button. Thanks for the information, I'll look for one of those.
