I have no experience with this but there may be a reset that needs to happen once the aux bat has been replaced? Proceed at your own risk, but maybe try disconnecting the main battery for a minute or two to reset all. Be warned, this may erase presets and other settings you have saved in the car. Failing that, or not wanting to chance it, call dealer for advice and or service. Good luck.
