I have an Autopage RS660. Its actually an older alarm now, I installed it when I first bought my Suburban in Jan 2006. Still working flawlessly though. Has remote start, 2-way paging, keyless entry, temperature sensor, dual zone shock sensor, glass mic, and 6 aux channels. I also added a DEI 516U voice module. So upon arming and disarming, it says "System Armed" or "System Disarmed ". Its also tied into the shock sensor, so if someone lightly hits my truck, it chirps and says "Protected by a Security System, Stand Back!".
