Hi all, I have a 2012 countryman. My sunroof was open during a thunderstorm. Water ran down the speedometer and in a few buttons of the radio. At the time the radion was in aux mode. Since then, the radio only operates in aux mode as it was before getting wet. The off/on volume dial work but other then that nothing. I've unhooked the batter for 30 minutes and reconnect and there's is no change. Anyone have any answers as to how I can recover radio functionality?
