Autool X200S Car Auto HUD Head Up Display Projector With OBD2 OBD II Interface Vehicle Speed Warning Alarm System Windshield Projector

1) Keep your eyes on the road:

At 65 mph, looking down for one second to check the speedometer means driving blind for 95 feet. Many accidents start during the time a driver glances down and fails to see sudden traffic changes ahead. Now, drive safely by never looking down to check speed again.

2) Know your true speed

Autool X200S HUD uses GPS to determine the true speed of the vehicle. There are several reasons why there may be a difference between the speed displayed on the car's speedometer and the HUD. These include:

-calibration set by vehicle manufacturers to read high to ensure their speedometers never indicate a lower speed than the actual speed of the vehicle.

-speedometer inaccuracy due to aftermarket modifications such as different tire and wheel sizes or different differential gearing.
