After listening to everyone, I hope my new Concerton will work! This is the only radio that would fit the hole and not get in the way of my cabinet door. Ok, that said, it seems pretty simple to wire? Not so, before hooking everything up, I wanted to make sure I had power to the unit. I have the speaker wires and then I have a green and white wire coming from the RV, on the back of the Concerton, I have the speaker wires and of course on the remote, I have a black and yellow wire (which I assume are conncected to the green and white wire) Must everything be wired first before it'll work? Or am I missing something here? Oh, I have a Puma 08. Thanks in advance:stars
