Mp3 player

I have an mp3 player and I want to somehow hook it up to my stereo in the car. I have the standard setup where it has a cd player and tape player deck. Is there any way I could add on an mp3 player to it?

Yuo've come to the right place. I've added an mp3 player to my cousin's regal, although a different car, same radio.

Refer to this thread, as i don't feel like typing it all again. http://www.automotiveforums.com/vbulletin/showthread.php?t=369646
