The device plugs into the vehicles On-Board Diagnostic (OBD-II) port. This port is the same place your mechanic plugs in his or her diagnostic tool to determine the health of your vehicle. We’re able to collect any information your vehicle shares via the OBD-II port, and share relevant information with you. In addition, the device has a GPS unit that can track location-based data. Insurance customers have the option to turn off location-based data at any time, because we don’t require it to log the miles driven. The device also has an accelerometer that measures changes in velocity and a gyroscope that measures the angle of the device, providing information that helps us find ways to make your life easier on the road.
