Audio Systems: Motorola Blue-Tooth kit, jeep grand cherokee, auxiliary input adapter

Question
I have a 2004 Jeep Grand Cherokee w/ factory 10-disc changer/in-dash CD & tape & recently got a Motorola Blue-tooth kit.  I had it installed but they weren't able to hook it up to the stereo instead it has its own speaker.  This works fine for making phone calls but i was also planning on connecting an mp3 player to listen through the stereo.  Is there any way to hook this up to the factory stereo?

Answer
you need this to input audio from the mp3
