My car being ex-demo has a tracker on but I never carried on with the subscription as my insurance were not interested in knocking anything from the premium.If it did get stolen and the police know it has a tracker on and they request it to be activated once more,surely Tracker are obliged to help,I often wonder this.I refuse to pay the subscription to aid my insurance as any damage once the car is returned and my no claims would be lost anyway,might as well get a new car.
