What is the OBD Driver ?

The OBD Driver is the gas mileage gauge of the car. It takes out information from OBD2 diagnosis connector of the car and calculates the gas mileage and display it in real time.
The OBD Driver uses the Android device and displays information in big-screen full color.
The "Serial Port Profile(SPP)" in your Android device is necessary to use this application.
Please buy the OBD Bluetooth device in yourself.
