Not sure if I'm missing something, have 14 Ram 1500 Express with uconnect 3.0 and a current subscriber to XM. When ever I have them send a activation signal, with the truck on it just says aquiring signal nothing changes. Not sure if I still need the antenna or not I assumed that the antenna was on top of the cab just behind drivers seat or if that's the radio antenna? Do I need to register with uconnect?
