I've had a Crown Signia for a few weeks now. One of my big motivators was reducing noise as much as possible compared to my 20 year old car. Mission accomplished there, but I am confused by the ESE and ANC question. Some people claim that ESE (engine sound enhancement) is present in the Crown Signia Limited, and that turning it off makes a huge difference. Same goes for the active noise cancellation, which should be left on. I got the Carista dongle and iPhone app to try to do this, but I hear absolutely no difference when messing with either setting. Am I missing something?
