I changed my batter a while back on my '12 CMS All4. I did not reprogram the battery module after the change. After changing the battery I noticed that the radio presets reset every time I turned the car off. It happens to both Satellite radio (it remembers I was listening to Satellite radio but always starts me on the preview channel), and on terrestrial radio, just blank presets. The clock does not reset and keeps time, along with everything else remembering correctly (bluetooth, etc). I have the HK Audio System with Navigation with every available bell and whistle. Has anyone else experienced this when changing the battery and not reprogramming the battery module?
