Review on Universal Vehicle Smart HUD Display by Pete Juarez

This is a very BRIGHT DISPLAY for SPEED. This device just points straight at you no matter what angle you mount it. I wanted it for the GPS compass and speed but it also has a mileage function. Easy to install. Uses a cigarette lighter socket. Calibration at engine start. DO NOT worry about inaccurate compass function after takeoff. If you move the car a little, you will get very accurate GPS compass readings. I love this device and it shows speed almost exactly like my speedometer but without having to look down.
