If I turn the radio anything higher than level 3 on the volume I can't hear the noise at all. With no radio but the windows down I can only hear the noise when at very low speeds or at stand still.

Is it annoying? Yes, but only because now I know it's there. Had this post never been created I probably would never have picked up on it since I usually have my windows down and/or have the radio on to at least volume level 5. So for now I'm not really going to be worrying about but it would be nice to see a resolution of this or at least find out the cause.
