Review on ACECAR Universal Dual System 3.5 Inches HUD - Head Up Display for Car with OBD2 GPS Interface, Speedometer, Engine RPM, OverSpeed Warning, Mileage Measurement, Water Temperature - Suitable for All Vehicles by Joshua Douglas

Auto 15 Infiniti QX50 readings pretty accurate OOB without calibration, although I read the manual in anticipation, not sure I disabled the alarm (this part of the manual is real confusing huh? ), but I haven't heard any sound yet. I don't have anti-glare installed, so my windshield reflects a double image, although the screen makes the HUD reflection very clean and clear, it also creates a blind spot near my vision, which I'm not very comfortable with. . In daylight, especially in direct sunlight, with no screen, the HUD's reflection is blurry, but I don't really need it in daylight, so this is a moot point for me personally. Reading at night is very useful even with dual display, you just have to adjust the brightness to your liking. The only thing I'm currently struggling with is getting the wiring neat and nice around the dash, which I'm still working on. Overall a good device for its price.
