AUX output

My original stereo os the cabbase 6 Cd slot in the head unit.

Im well aware that underneath my drivers seat is a AMP of some sort.

The other day I was messing around with the audio controls and all of a sudden rather than having just FM/AM/CD it now comes up with AUX. Is that saying I can plug my IPod in somewhere or is this something else?
 
You can hard wire into the red plug in the back of the Cabasse unit, have a look at my project thread, I did this so I could wire in the audio out from my Parrot (which controls my iPod).
