## Features

- 【OBD2 +GPS Dual Model and System】This heads up display reads the driving data of the vehicle through the OBD2 platform of the ECU computer, such as speed, fuel consumption, water temperature, voltage, etc. It instantly reads the driving information under the condition that the large field of view does not shift during the driving of the car, avoiding the driver from looking down at the instrument during the driving process to affect safety.
- 【Safety Driving Function】Additional instrumentation is equipped with several fault alarm functions: low battery voltage, high water temperature, RPM, over speed, fatigue driving, engine fault, and excessive tilt angle, making driving safer and easier.These alarm functions can help you avoid accidents and keep your car in good condition to ensure your driving safety.
- 【Fault Code Clearing】- When the engine warning light in your car's instrumentation comes on, it indicates that something is wrong with the car, but with the F12 speedometer, you can clear the codes yourself.
- 【Multiple installation and easy to install】This digital speedometer comes with OBD2 cable, just plug it into the OBD port to use and read your car's data. It will not change your car's wiring or damage your car's surface. There are two ways to mount it: with a bracket on the center console of your car, or with a swivel bracket on the front windshield or A-pillar, depending on which position you prefer.
- 【Upgraded HD Screen】This digital speedometer is equipped with a high definition TFT LCD screen that displays information in a more colorful, clear and slim design with ambient lights around the edges for a high-tech feel.
