Pioneer 6 disc changer - how to use audio in for MP3 player/phone

[sweetm79]

We just recently purchased a 2005 Adrenalin with the Pioneer 6 disc changer. It has a place for audio in so I got a cable that runs from the microphone on my phone to the audio in on the stereo...but I can't figure how to change the input. I see the buttons for cd, am, fm, etc but nothing that would allow me to switch the input to the audio in. Does anyone know how to do this?

There should be a button that says input or aux. If you post a picture of your unit i might be able to help you out a little better.

I'm not sure if that link will work. I don't see any buttons for aux or input. I tried the menu button but that only gives options to adjust treble, bass, etc.
