Great alarm system. If hooked up properly with a back up battery. A alarm is as only good as the install. The range is great compared to the rsx3.5. Nite and day diffrence. Add A gps unit to it and have a killer combo. I install this unit all the time. Real user friendly on a noob install compared to the compustar unit.
Here check out a thread that we have on ht. This will help you out alot if you are going to do the install yourself.
