Review on Upgrade Your Car Experience With ACECAR'S Digital Heads Up Display - Accurate Speedometer, RPM, Water Temperature, And More! by Adam Price

Update: seller showed me how to calibrate the speed to match the truck now it works fine also it's hard to see during the day need to fined a spot with no direct light.I first installed this in my 2001 Mitsubishi Galant. It didn't work the reflector just kept going up and down. So I installed it in my 2007 Chevy avalanche and it worked fine. I like the idea of the reflector folding down when off. Unfortunately like all other HUD displays this one is also inaccurate. It shows the speed 4 miles faster than the actual speed. I didn't see anywhere in the instructions if it's possible to calibrate the speed.
