HUD setting
HUD display information is from ECU, because when producing car, there is a difference between vehicle dashboard and ECU , then you can enter the setup mode to fine-tune the HUD display value, in order to achieve exactly the same value as dashboard. We have adjusted HUD according to the general test values at the factory, if you find HUD display information is different from dashboard,then make the following adjustments:
Reflection film installation
Please Note: HUD project the display information on the car front windscreen , because the windscreen is double, which will make double image on the windscreen when display.The double image of car will be different.If you can see clear the display information, then there is no need to use the reflection film. If there is a double image, then please use the reflection film.
First, please put the supplied non-slip mats in front of the dashboard, and then put the HUD on it.
Second,please stick the reflection film on the windscreen.
The reflecting film should be pasted right above the host machine and it should be able to reflect the whole display screen.
HUD installation
1 Know the type of your vehicle. When purchasing HUD, you need to choose the type of vehicle that meets the OBDII standards (or EU OBD) for normal use. Open the engine hood and find the sticker below it (see the below picture 1), if it has words like OBDII CERTIFIED, then it can be installed.
2 Find out the 16 pin diagnostic link (see the below picture 2) of the vehicle and connect it well with OBDII connecting line.

Stopped working after 1 month
This product worked great when I first got it. Following the tutorial video someone made on Youtube made it super easy to calibrate, and I really enjoyed this unit! … for a month.And then suddenly it went crazy and started beeping and making all kinds of random light flashes. I turned off the car, unplugged the device, and waited for a bit. After plugging it in it turned on normally but I lost ALL of my calibration and preference settings. So, annoyingly, I reset everything. And it worked for one drive. Next drive, it was back to default settings, flashing randomly to voltage mid drive (while I’m relying on it for MPH speed to safely drive loved ones in my car), nevermind when it was in speed it was back to Km/h, which was super disorienting IN THE MIDDLE OF DRIVING.It’s going in the trashcan, and I’ll be trying a competitor’s unit to see if it does any better.

Excellent speedometer good polling and refresh rate, bright enough to be seen against the Australian sun. Can be recalibrated for accuracy, and is probably only limited by the specific precision incumbent after encoding and rounding from your cars on board speedometer. I have been using it for one year in Queensland, without the included black film that is just distracting and unnecessary. Note that the film may present a slightly clearer projected image. Depending on the thickness and laminate of your windscreen. Give it a chance without the film, within a few days I stopped minding the imperfect reflection. After a couple of months I had to concentrate just to observe the imperfection because my eyes/brain were tuning it out.
