How does the Griffin ITune Fm player work?

I see by the pictures that it piugs into the IPOD and you can set the frequency from there,but how does it get from the ITune to the actuall car stereo?Because from the pictures there are no cords that go from the ITune to anywhere else.Is it wireless or am I just missing something?
