The Area Alert service lets you know if your car is in within your predefined area. For example, if you have lent your car to someone who has moved your car into or out of an area, you'll be notified via email or push notification so that you can take the appropriate steps.
You can create up to 10 areas, but you can only activate up to 4 alerts at the same time. Additionally, you can select whether a notification should be periodic, once-off or always active. The Area Alert service tolerates up to 25 meters of difference before sending an alert.
