This system can be linked to an existing alarm and/or geo fence. If triggered, it will send an SMS from anywhere in Europe to up to four phone numbers. Using the supplied co-ordinates, the user can then plot the exact vehicle position on the provided PC mapping program. Another handy feature is that you can send commands to the car, such as activating the hazard lights or immobilising it when it comes to a standstill.
