    It's predominate near the rear view mirror, but travels the perimeter of the
    glass! Is this the antenna for the key-fob remote entry? Or is it some sort
    of capacitance rain-sensor for the automatic wiper control?
  2. Sounds like the UV shield for the Adhesive thats used to hold the glass in
    place. Usually its black with patterns to feather out the edges.

  3. Antenna for a cell phone or OnStar?
  4. Nah, it's based on garlic consumption

    Thanks! Your answer makes the most sense. I've recently learned that the
    rain sensor is a small box attached to the rear view mirror (seems part of
    the mirror at first glance). It houses an infra red emitter-detector that
    emits light at a 45 deg angle. If the light is reflected back un-obscured,
    it's not raining. The degree of light blockage is determined as the amount
    of rain fall!
