Has been over a week since I did a reset on my 21 sierra and the settings are still as I set them. Awesome!

I did the factory reset two days ago. Has kept settings so far. This is the longest the settings have been kept. Will keep you all posted.

I have the same problem with my equalizer settings. The phone volume, voice volume, and ringer volume also drop to no volume. Can not even hear phone ring. Service manager said “known problem” and will check for an update. I called again today for an update.
