Great little HUD. Only think I noticed is the MPH is off by 1 or 2 MPH on this unit but that is good in a way and will help in over speeding.

I have a JDM import van, which shows kmh instead of mph. While this isn't a big deal to remember the major speed milestones, this makes it extremely easy. Works just fine with or without the reflective screen, but the screen included does make it brighter and eliminates a double image which I was getting without it. Perfectly visible even in bright sunlight.I have it wired to a USB power converter under the dash to hide the wire, turns on and off with the car.

Was cool when it could get a GPS to determine my speed. Too inconsistent to be used as intended. I'm glad some people have had success and enjoyed this. Me, nope

The installation was pretty simple for me but I am a person that also installs my own aftermarket radios, kill switches, and amplifiers in my personal vehicles. Concealing the power wire was probably the most time consuming part of the installation. The display is crisp and visible in all lighting, but especially during darker hours of the day. My only complaint is that the speed is off by 2-3 miles per hour on average and it is always slower than the speed shown on my vehicle's stock digital speedometer. There is also a noticeable lag, for example my 0 to 60 on the factory dashboard speedo takes about 3.2 seconds which exactly matches an actual stopwatch time but on this GPS heads up display it takes 4.5 to 5.2 seconds during repeated test runs. I guess the delay is not so bad if you just use it for cruising or more practical daily use, but just don't accelerate too fast and you'll be fine with this Yaouzicn unit.

The speed adjustment is set to 107 by default. You need to change it to 103 to have an accurate GPS speed. Other than that, I've had no issues with it. I love having the speed right in front of my eyes. I tried it in several different places, but I ended up putting it just below my line of sight. I can see straight ahead with no issue, and I can glance two degrees down to see the speed.

I don't write reviews often, but man, This thing is cool! Put it in my 2001 audi TT and while I did have to adjust the speed down, once I did it has been INSANELY accurate for just being GPS and not plugging into OBD. Also, the display works great and adjusts perfectly for day and night. I haven't even put the shiny film on my windshield because there's no need. Was shocked that this works so well for just $30.

Good luck if you can figure out this ridiculous menu system. The speed is also faulty. When the car is stopped it still shows 0.3 to 0.6-mile speed. Do not waste your time buying this product.
