JM-VG02U – INS-aided OBDII Tracker

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.

  • INS-aided GPS Tracking

    Ensure constant tracking in the area with poor GPS signal or even without it.

  • Mileage Accuracy ≥98%

    Precise mileage calculation based on a unique algorithm, the mileage error can be less than 2%.

  • 9-36V Operating Voltage

    Compatible with a wide range of input voltage, able to work on diverse vehicles.

  • Fatigue Driving Alert

    Get alerted of the situation that a driver has continuously driven over a long time.

  • Driving Behavior Analysis (Advanced)

    Receive alerts when any of 8 kinds of dangerous driving behavior is detected.

  • 6-axis Accelerometer & Gyroscope

    Sensitive detection of linear acceleration and angular velocity.

  • Effortless Installation

    Simply plug this device into OBD II socket, you don’t have to turn to professionals.

  • Multiple Alerts

    Instant alerts for atypical events such as low battery, speeding, abnormal vibration, etc.
