Do the 05's have an interior motion sensor built into the alarm system. My alarm went off the other day and nobody was around the car, however, my windshield shades fell down. Was just curious if they could have triggered the alarm. Don't know if it's related but what are the little circular objects in the corners of the overhead lights above the rearview mirror? They look like little tweeters. Just curious.

 

There is a tilt sensor as well as the interior motion sensor (those circular objects on the mirror).
I was jacking up my car the other day and forgot I had the alarm set...man that was load inside the garage!

 

Cool, thanks for the info Pony.
