I connected everthing together and it works just fine. However, when I turn off the key it will continue to stay on? I connected all the wires correctly per the manual. My other HU is on top and it powers down no problem, and their connected to the same wires? I connected both the yellow and the orange to a ignition off source. This way there is no battery drain with the key off. My memory presets stay also, even for the radio function. What's going on???
