text: There is also another use for the phone hookup to the car feature and that is so that someone can get notified if they do happen to have a family emergency. This is so that if someone does happen to have a family emergency and they are in the car already all they have to do is drive over to where the family emergency actually is. This is so that you can get notified if something bad does happen to someone's family member they won't have to wait until they get home to find out what happened.
