Nice work Karen, but I want to clarify my recommendations about the grounds. Pin 13 is the RSE enable, which should be wired directly to a ground, one of the nearby screws should do. Pin 14 is the signal ground for the AUX input, which should be kept separate from the vehicle ground and pin 13 for best results.
