【M1 hud】M1 heads up display for cars is a GPS mode head up display. Unlike most head up displays on the market, our designers have fully utilized the characteristics of the windshield to create a simple white windshield HUD, which is easy to install and plug and play.
【Design concept】Heads up is very simple, the data projected onto the windshield cannot be too complicated, otherwise it will block the driver’s view. So we designed it as a very simple speedometer, presenting only the most important data of speed in front of the driver’s eyes, at a glance, simple and clear.
【Main functions】M1 heads up display can display the speed, GPS compass shows the direction, also can show the driving direction, also has a speeding alarm and fatigue warning function, the speed has MPH and KM/H two kinds of units, can be adjusted in the settings. When speeding or continuous driving time is too long, the product will beep to remind the driver, like a safety monitor, always remind the driver to pay attention to the safety of driving, placed in the car a mini M1 HUD will certainly add a lot of fun.
【Automated Brightness】Digital speedometer for car is embedded with advanced light-sensitive elements, which can change according to the brightness. When the light is strong during the day, the product will automatically brighten, on the contrary, when the light is weak at night, the brightness of the product will also automatically become dark.You can also manually adjust the brightness of the product.
【Instructions for use】Our windshield speedometer projector is easy to install, plug and play, just use the usb cable included in the product to connect the car and the product, start the engine to power on and use. When you notice the small icon on the product flashing continuously, it means the product is collecting satellites, the speed will only be displayed when the device searches for satellites.
【Suitable for All Cars】Collecting speed from GPS satellites. No relation with the car engine, can work on all vehicles on the market.
【Note】Please note the following three important information, ①In garages, overpasses and dense buildings will affect the search speed ②When the same GPS device is installed in your car, it will also affect the search speed of this product, i.e. two GPS devices cannot be placed together ③When your car has metal film, it will also affect the search speed of this product.
【Special reminder】The working voltage of this product is 5V, and it is prohibited to use voltage higher than 5V for power supply.
【FAQ】①No vehicle speed: After power on, the satellite icon flashes to indicate the search status. Please move the car to an open road and wait for the satellite icon to stop flashing before it can be used normally.② Incorrect display of driving direction:When there is no vehicle speed, the satellite cannot distinguish your driving direction. It can only display normally when the vehicle speed exceeds 5KM/H.③The speed is still displayed after the car stops: Underground parking lots, tunnels, and under overpasses may cause unstable signals and satellite drift due to obstructions. Please drive your vehicle to an open road surface.
【High definition film pasting method】① Clean the glass in the projection area. ② Remove protective film 1. ③ Paste vertically on the glass. ④ Remove bubbles. ⑤ Remove the protective film 2.

Good value, easy setup.
This is easy to set up. The power cable was the right length and was simple to tuck out of sight. The small HUD projector and its sticky mount work perfectly. Adjusting the speed to match the speedometer took only two tries. Once turned on, it finds GPS right away and gives accurate speed and time.The windshield HUD screen that was supplied was too small, did not stick to the glass, and was not good. Replaced it with a larger 7 1/2″ and better one.Overall, excellent value for the money. It gives speed and time accurately. It is safer driving with HUD information, so one’s eyes are on the road. This unit delivers.

Good simple speed indicator
This is a good simple HUD unit that can display time, speed and compass direction using GPS. You just put it on your dashboard and let it reflect off the windshield. There is a film you can attach to the glass to make the reflection clearer. There are different display modes, letting you choose which elements are displayed.I’ve read that some people say that it is inaccurate. For me, the default settings made it display speed that was 10mph too fast past 50mph. I was able to adjust it so that it was within 1 or 2 mph from 0 to 65mph. Press and hold M to enter the menu. The first screen will show an adjustment value (I think default is 107 or something like that). Lower it to 102. Press and Hold M again to save and exit. That worked for me. The instructions are not very clear on that, but basically if it is showing too fast a speed compared to your speedometer, adjust that value downwards. If it is showing too low a speed, adjust it upwards.Limitations:1. It uses GPS, so it takes a moment to find the signal when you start the car.2. It uses GPS, so when you lose the signal (like in an underground parking) it will show 0mph.3. In bright sunlight, its projection can get washed out.4. If you wear polarized sunglasses, it may filter out the display as well.All in all, for the price, it’s a good unit if you don’t need anything fancy.

Works great… sometimes
This was easy to install and I bought a hardwire kit so I could tap my fuse box and hide the install. Looks great, used 1/4 inch black plastic auto wire conduit (about 4 inches worth) to hide and protect the exposed wire on the dash area from direct sunlight damage and make it look clean. The unit comes on when I turn on my car and gets a satellite signal within 10 seconds so by the time I back out of my garage and drive to the end of my street it starts working. I had to follow the directions to fix the speed calibration and it is dead on the correct speed now. I have had it installed for about a month now and it is getting very hot here in the Dallas TX summer sun. It gets covered by my sun shade while it is parked at work.Not sure if this is due to heat but my wife and I took a drive out into the country a few days after I installed it. It did well for the first part of the 3 hour round trip but on the way back, it locked up on 0 mph and 7:00 and that did not change until I restarted the car after we had been back for about an hour. It did not do that again until yesterday when I was at lunch. I got back from lunch, turned the car off, went inside for about 2 hours then it did fine on the ride home, no issues. Not sure if this is heat related.I am able to see it without using the provided reflective static window cling used to reflect the light better during bright day light but I may try the cling soon to see if it helps during the day. Also, the unit has an auto dim for night use that helps a lot and looks nice. It looks the best at night or sun rise, sun set. The numbers for MPH are big and easy to see even without my glasses. I can also read the smaller clock without glasses. Its hard to see the compass and the timer numbers. Looks really good with my glasses on, very clear and looks very clean. Unit is black and very small and blends into my black dash.For the price its a nice little gadget but if I were to buy another I would get one that attaches to my OBD port and use the cars computer data to get speed and other info but also has a GPS to give a compass. Maybe $10 more.Nice little gadget. Easy way to make an older car feel a little more up to date and a newer base trim level car feel a little more luxury.

Disappointed in response of unit. Speed and rpms.
The speed registers as 5 mph fast which is why I got this because my dash does the same. My gps backup mirror is correct. Also the rpms are not registered very well when hooked into the obd slot. The buttons should be on the other side so they don’t face away from the driver. It’s nice but could be a bit better. I would say save the 20$ and get the ten bucker.

Easy to read.
Great product, after installing you can easily see your speed day or night without having to take your eyes off the road.

The AZIJYV Windshield Projector is a solid, useful tool that does exactly what I need it to. While it has its pros and cons, the overall utility makes it worth having.The main drawback is that it’s hard to see in the daytime, especially with the glare from snow on the ground. Also, the speedometer is off by about 4km/hr, though that’s a minor enough gap to manage. Overall, it’s a very handy gadget for the price!
