You can create boundaries (or what many people call geofences) around areas that you want Elo GPS to send you an alert if your car enters or exists them. Like say for example, your teen is driving to college. You can create a boundary around their dorm or the campus. Elo GPS will notify you immediately once they arrive.
Elo GPS lets you draw your own free-form boundary or use preset circular or polygon shapes. You can set up alerts to notify when your car enters, exits or both. You can add and delete boundaries on the fly.
