I have two of this system (one on each of my Legends).
Couple of corrections though. The dual-zone proximity refers to both the inside and outside sensors. There isn't one for each of the zones. The primary zone is the interior which will set off the alarm if movement is sensed inside the cabin area. The secondary zone is the exterior which sets of a "screach" when someone comes too close to the car.
The other thing is that the AG4 does not come with a glass sensor as standard, but I believe that you can add it.
As for Black Jax, if you choose to activate it, it is constantly on. It doesn't automatically sense a car jacking, but looks for situations that would hint towards a car jacking. However, if you choose to enable it (it can be turned on and off), you have to deactivate it everytime before you drive the car. It automatically assumes a car jacking.
As for price, I think that the average going is $1200.
