Review on 🚗 Enhance Your Driving Experience with the Pyle 3.5’’ Car HUD - Head-Up Display Multi-Color Screen Projector for Vehicle Speed & GPS Navigation Compass - PHUD12 by Luis Watts

So I noticed that the mph reading is always +5-8% this one if you are driving at 55 mph it reads 59-60 mph at 40 mph it reads 42-43 mph This prompted me Constantly comparing the actual mph in the car and the mph on the HUD, which negated the benefit of having a HUD I was actually curious if my car's error was in mph, so I used google maps used to show the miles per hour and the car was correct and the HUD was off by the above amount note: great price and love you didn't have to connect me to the ODBC port n, but I didn't like that I couldn't calibrate or adjust the displayed miles per hour. this turned out to be more dangerous as I always looked away from the road to compare the MPH readings. :sad panda:
