I have mine set to on. I noticed that when I'm in the back seat it sounds like it's cutting in and out. Even passengers have noticed it by saying "I think your speaker is damaged." The on/off sound is coming from the speakers behind the right and left rear passenger seats toward the roof line. Is this a bug or is this a feature? Sounds odd. When I turn off the neural mode, it goes back to normal but the overall acoustics in the vehicle sound flat. Hmmm....
