i think im going to get one a little later since I just bought the alarm and the tracking system. this would work great while the car is running or carjacked. I just cant remote start to far away with this installed. I would only remote start where I can see the car anyways. good find, seems to be a good product. incase someone might have a gps jammer, they would not be able to get away with this on the car. all three together makes it even more difficult to even thinking about stealing the ride now.
