Some SOB tried to break into my car about an hour ago. Tilt sensor was triggered. I have the remote start module installed, so my iPhone alarmed, waking me up. No smashed glass, no damage to car, nothing stolen. Just had a CB installed. Looks like I'll have to take down the antenna when not in use and possible radio, which will be a pain because it is semi permanently installed. Viper system was well worth its weight in gold.
