They do sell a more expensive unit that will track were the car is AND notify the police. The only problem is that not all police cars are equipped with that system. And not every area in the US or more specifically Atlanta has it. So EX. Car A is stolen. with in 5 min if it being taken you are called on your cell every 15 min and so are 3 back up people on your list if you do not answer. 2. The signal goes off and within that 15 min IF a cop has that system in his car, he will be sent a signal to were the car is and that it is being stolen. Then he can go catch the guys. With that system, the cars are found with in one hour or so of it being stolen. But that is a big IF... IF the cop has that system in the car and IF the cop will actually do somthing about it.

I belive that it costs about 900 for the "top of the line"
