Review on 🚘 ECOOLBUY Upgrade S7 Car Universal HUD 5.8" HD Screen Head Up Display - GPS/OBD2 Dual System with OverSpeed Warning Timer, Compass, Engine RPM, Mileage, and More by Brad Collins

1. It only works in GPS mode for my car.2. This HUD works but needs improvement.3. The clock is accurate.4. speed accurate.5. I don't like turning the device on and off. I thought it would turn on and off automatically when you start or stop the car. 6. Some icons are very large and easy to read.7. The compass symbols are too small and difficult to read.8. The reflective film makes the display very clear BUT it is difficult to perfectly match the display.9. It can also look distorted if your windshield is curved too much.10. It is also difficult to get a reflective film perfectly smooth. A credit card used as a small scraper helps.11. If you remove the display unit from the dashboard everything will need to be aligned when you put it back in. 12. I prefer a "double" or "ghost" head-up display and don't use reflective film.13. The instruction manual is surprisingly clear and understandable. Some wording could be better.14. There are only two buttons on the device. One is a small "rocker switch" that can be swung left or right, or pushed in. The word "VERTICLE PRESS” is used in the operating instructions. It simply means "Push the button inward".15. The adhesive pad keeps the HUD display on the dashboard very securely.16. Night time: the display is very bright.17. Cloudy day: the display is legible18. Strong sunlight: the display becomes blurry.19. Customer service answered my questions. 20. Verdict: If you can tolerate a box on the dash with a visible cable and a dual display on the windshield, then you might like this HUD. I hope improvements can be made for larger compass icons and better reflective foil.
