TECHLINE SUMMARY ARTICLE - WHEN PLAYING THE AUDIO UNIT, ARE YOU HEARING A NOISE FROM THE SPEAKERS THAT SOUNDS LIKE A HELICOPTER HOVERING OR A CD SKIPPING? THIS NOISE SEEMS TO BE INFLUENCED BY THE NEURAL (SURROUND SOUND) SETTING. WHEN ITÂ’S TURNED OFF, THE NOISE STOPS. WHEN ITÂ’S TURNED ON, THE NOISE STARTS UP AGAIN. THIS NOISE IS ALSO CANCELED WHEN YOU CYCLE THE IGNITION.
