I really hadn't thought about the alarm until tonight. I was reading a thread on here about this guy's ex getting broken into, and my town is pretty crappy so I wouldn't be surprised if someone stole anything of value from my car the second they see it. I have gotten lucky so far because I live in the country, and I don't have anything worth risking trouble to steal in the day, but I don't think a in dash dvd would have a chance.
