I have been doing some more reading and it states that the system will send an emergency signal if an accident occurs with air bag deployment and/or the emergency tensioning retractors is activated. Even thou I use the car 98% of the time, my concern is for the sake of my wife. She has NO sense of direction, I have bailed her out a couple of times already. If something mechanical should happen I know she will call me, but if I'm out of the area I can't help her.
The president of the dealership called today and we are working out an agreement between us to get the hardware and installation at a significantly reduced price and possibly a no charge one year subscription. I'll keep you posted on the results.
