There is a co-axial cable with a round plug that carries a signal from the antenna to the headunit. The signal is then decoded into crisp stereo sound. No that's not the wire I'm talking about. On my Alpine it's a blue wire (and I have no idea about your headunit) that signals the antenna to go up and down.
Find your headunit manual on the net and check the wiring guide at the back.
