I think you can reflash that module, I havent used the 44 yet. There should be a usb port on it. try to reflash. Ground to the chasis of the car make sure theres less than 1ohm resistance. I recommend pac-audio interfaces I made the switch because there gm harness' would do stupid crap like you describe

2014 might be different it does sound like you are going up against firmware. If you dont give a crap about onstar the just grab your ignition from the switch or bcm fuse panel
