Review on 🚗 AUTOOL X360 5.8'' Car HUD Head Up Display Reflective Film 3 IN 1 AUTO OBD Smart Car HUD Holder Mount Multi-Function With TPMS System KMH/MPH Air Leakage, Voltage Levels, Temperature Alert, Electric Power Alarm by Maxwell Thomas

If you want a functional, accurate, and highly visible HUD, this is it. It's easy to connect by simply plugging into the OBD2 connector. It takes direct readings from your vehicle on a very clear display. I've tried the ones where you use your phone as a display and they've only come in handy at night. The only negative is TPMS. The caps are awfully big and you can't hold a Psi tire pressure gauge. (I wrote to the company. They said there is one. Politely of course). Once you learn how to translate the user manual, it will be very easy to use.
