All the lines I've connected seem to be correct (I'm not sure if I hooked up the grounding wire to the correct wire coming out of my car though, as my car had no previous radio in it), but when I turn the car on to accessory, the radio only lights up, but nothing comes up in the display and pressing the power button does nothing, and I hear the cd player whirring and after 5 seconds or so, the lights and player shut off and don't come back on until I disconnect and reconnect what I think is the corresponding grounding wire from the radio to the car. So am I hooking up the grounding wire to the wrong wire coming out of my car causing the player to not function correctly, or is it just broken?
