Sorry to hear about your loss. Car alarms are only heard by their owners, if those owners are alert and within ear shot. I wish car alarms offered easily customizeable tones so one could be distinguished from the crowd, like all the various cell phone tones. One reason I'm reluctant to upgrade my audio system is that OEM audio systems rarely, if ever, get stolen. I periodically leave my VX in Fresno's long term airport parking for extended stays with little concern for its welfare. However, if I installed a quality sound system, I wouldn't be able to sleep nights when I was out-of-town. Mind you, every time I wander around Best Buy or Circuit City, I'm tempted to throw caution to the wind and go for one of those kewl techy audio setups with XM and integrated GPS. BTW, I've been pleased with USAA for all my insurance needs for some 24 years. Though their rates may not be the lowest, they offer the highest quality service. With the few auto and home damage claims I've submitted over the years, they were always on my side, proactive in my interest and supportive.
