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 with this Head-Up Display Speedometer. You may also set an overspeed warning with the touch of a button. When the preset speed limit is exceeded, a visual indicator lights up and an optional alarm beeps (for up to 15 seconds) to remind you of the speed limit. (Device does not detect local speed limits.) 

Know your true speed
 The 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.
