🚗 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) Review

This HUD is installed on my 2019 Subaru Crosstrek Limited with a STARLINK subscription. I like it, but unfortunately I have to delete it! Pros: Easy to install, great price. Cons: 1. The speed doesn't match very well, even after adjustment there is still about 1+/-2 margin. RPMs are for illustrative purposes only and do not reflect actual engine RPM3. I'm having trouble with STARLINK emergency services. I get an error code every time I start the car after installing this HUD with an OBD…

An excellent option for your money. Photos shown: morning sunrise drive, cloudy day, night time. It can definitely be used without the 3-inch sticky clear reflective screen, but the reflection won't be as strong depending on the device. The screen is HUGE. The only downside is that the higher you are, the higher on the window it ends up. transparent but not crystal clear like the windshield itself. So it might seem like a bit of a distraction until you get used to it. I have 6ft 4in and this is

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

I chose this one because it would work with OBD or GPS and I wasn't sure if it was OBD II compliant although it was OBDII -certified was called. Of course, OBD doesn't work in my 2006 Xterra. But the GPS worked perfectly. I really just needed speed and timing and he has the ability to show just that. Put on your reading glasses to read the manual and study it first before delving into it. The speed was 5 too much for 70 so I changed the default 107 to 102 and now the speed matches perfectly. I…

Really neat device. When connected to the diagnostic port, it is as accurate as possible, possibly with a few ms delay. I didn't check the GPS because the diagnostic port was working fine, so I can't comment on that. Works great on my 2018 Chevy Truck. Because these HUDs simply reflect what's on the dashboard on the windshield, glare on the device sometimes becomes an issue around midday in the sun or even on bright, foggy days. The companion film attached to the windshield, which is used to…

This is a tiny display. It shows the direction of the light, tachometer, speedometer and clock. All useful information. That's where the pluses end: - The speedometer and touch poll the ECU once a second. maybe even every 1.5s. It's so heavily lagged that it's really useless for city speeds; At best, you can use it for highway driving where your road speed and engine RPM don't change much or rapidly. But everyone has cruise control (although many people choose not to use it), meaning that if…

I should have known better. Even though I knew it wasn't going to be an airplane HUD, I still had hope. This HUD (HUD-M12) works in either GPS mode or OBD II mode. I've only used OBD II so I can't comment on how well the GPS mode works. The "installation" is very easy, so I'll get straight to the heart of the report: the display. I was interested in seeing the altitude, distance, time and speed. Unfortunately, you're stuck with a relatively large tachometer that you can't remove, compass…
