I am having trouble getting the power wires right for my deck. The deck has the basic ground, ignition and battery. My question is what is the ignition and battery coming from the BMW. I wired it up so that It finally works, but it only works when the car isn't on, just lights and everything on. So can someone help me wire this up right. Please, I am starting to get mad, I need music when I drive.
