I'll start...
Three days after I installed M3, I went to client. After 3 hour meeting, went back to my car and the DIC (Driver Information Center) gave me a message that I had never seen before - 'Theft Detection.' My first thoughts were that something was wrong with the car's computer. I had set my M3 to high sensitivity for the 'parking monitor.' I don't know why the thought occurred to me to check the M3 files, but it only took a few minutes to find video of a guy in a red hoodie staring inches away from my windshield. The camera has a kind of 'fish-eye' effect, so the guy looked really goofy. I downloaded the files to my laptop and took it into the college's security office, and they knew exactly who this guy was. Two guards immediately left because they knew this dude was in class. Don't know the outcome, but if my M3 helps prevent other prowlers, it did its job!
