The latest, small update seems to have fixed the known issue with the Equalizer resetting noted by a number of owners. It worked..... my settings now remain as there were set when the X is powered off. Recall in a prior release (I don't track each note) Tesla added two additional controls for the Equalizer -- five adjustments across the spectrum. Unfortunately, when the Model X was powered down for a period of time, the controls reset to the buttons mid-range.
