The JM-VG02U is an OBDII vehicle tracker that can be installed effortlessly. With the built-in 3-axis accelerometer, 3-axis gyroscope and a practical algorithm, it can detect 8 types of improper driving behaviors and prevent dark spots, even in areas with poor GPS signal. Its improved system of alerts increases the safety of both the drivers and the vehicle, while at the same time reducing false alerts.
