I'm not a subscriber. Is there any way to remove it from the source options? When I'm hitting the source button, or the up/down button on the steering wheel it always takes me to the XM radio. I can't seem to figure out how to get rid of it. I know the car has XM, and I'm not suggesting removing the radio, I just don't want the up/down button to immediately take me to XM every time I'm tuning to change the station.
