The '07s have a hidden owner viewing sensor designed to reduce the
hours wasted by owners looking at their cars. It's pretty sensitive,
so just stop looking at it.
ohh, been a long time since I've posted but I had this same thing when I first got my car and it turned out that I was putting a sun blocker thing in the window and as it heated over time it slowly moved setting off the alarm... that was such an annoying and weird problem to diagnose! Maybe that helps?
the stop message on the CD player I got every once in a blue moon....usually occurred after putting in a cd that I burned from my pc.....fidgeting got it to go away
