Today I decide to play a bit with the audio coming out of the back of the CD Changer.
As some of us know you can`t get audio in with the AUX In on radio module 2002 or lower, my cd changer does not use the coax cable on the back, it uses 3 cable for the audio signal( low level signal ) .

I managed to input signal from my Ipod to the radio using the plug that plugs on the back of the cd changer….

Later I will have some pictures and more info as far as what each wire is for and how I found out.
