Audio Systems: auxiliary audio input, factory radio, pin plug

Question
I have a factory Delco am-fm/cd player in a 2001 Grand Prix & would like to know what I need to do to install a audio input jack somewhere on the front of it so I can play my ipod without using a fm modulator. (ipod integration to factory radio?)

Answer
you need to convert the  cd changer port of the radio in to aux you need the GM9-AUX  IF THERE IS A 9 PIN PLUG IN THE BACK OF THE RADIO most of them have it 95%  but if you have a 10 pin plug in the trunk you can use the GM10-AUX
