So I just bought a Pioneer DEH-4500BT head unit and I've connected it all up apart from the aerial because I don't get how this works here. How picture 1 fits picture 2. I bought an ISO to DIN adapter for the sake of it when I ordered the radio but the female end of that doesn't fit the aerial of the car. So I'm stumped. Any help would be appreciated guys.
