Review on 🚗 ACECAR Upgrade Dual Mode Head-up Display - OBD2/GPS Windshield Projector for Speed, Overspeed Warning, Mileage Measurement, Water Temperature, Direction - Perfect for All Vehicles (M12) by Brian Trotter

In the end it's just a speedometer. What, because that's what I basically want, okay. The directional sign is so small that you need a magnifying glass to read it. It's in the rpm range, which I can't read either, and nobody wants or needs that anyway. Other things like water temperature are fine but who needs them. What is displayed, and I don't know how to get it from the display, is something that says liters per 100 kilometers or something like that. As far as I'm concerned, I don't see how this can be something that anyone in the US wants or needs. The speed seems to be displayed correctly and as I said, that's what I wanted, which is why I'm giving it 3 stars. . But it's generous, as it's only visible in dim light, best at night, and is impossible to see or almost indecipherable when driving in the sun when sidelight of any magnitude is present. In general, I want to save my money, but I'll do what I can only do from the speed shown.
