【What is M22 hud】M22 is a GPS mode flat screen display, unlike most flat screen displays on the market, our designers have made good use of the windscreen to turn M22 into a new windscreen HUD
【Design Concept】This GPS speedometer is a novel design with a colour scheme for the first time. It presents important speed data to the driver at a glance and is simple to understand
【Main Functions】The M22windshield speedometer projector displays speed, clock, travel time and distance travelled. It also has an over speed alarm function and a GPS compass to show the direction（The compass needs to locate the satellite before it can be used. You can try moving the car to an open road surface.）. Speed is available in MPH and KM/H, which can be adjusted in the settings. When there is an over speed, the product will emit a beeping sound to remind the driver, which is like a safety supervisor, always reminding the driver to pay attention to driving safety, placing a beautiful M22 HUD in the car
【Automated HUD】The advantage of the digital speedometer automation is that it turns on automatically when the car starts and turns off automatically when the car is switched off, which is very convenient and you don’t have to worry about the product not being able to turn off. A gentle reminder, if you are not driving for more than a week, please remove the product and put it in the drawer
【Instructions for use】 Our product 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
【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
【Reminder】Inaccurate speed: Check if the unit is correct, kilometers (KM)/miles (MPH), (refer to the 5 settings for speed unit switching). You can also adjust the vehicle speed, such as the instrument displaying 100 km/h and the machine displaying 105 km/h. Adjust the parameter value to 102.During the day, the data cannot be seen clearly and there is a reflection: stick a reflective film to make the data reflect on the reflective film. You can also enter the fourth setting to adjust the brightness. 0 is the automatic light sensing mode, and 1-11 is the manual adjustment. You can manually increase the brightness.

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.

Not soldered, good enough on the power port
It worked for about a week.Then, the plugin, where the power goes to it broke off inside

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.

Should work well on a car but not on my big rig
Will work for a car but not for my big rig as my windows is strate. Will be sending it back for that reason. But overall I like it.

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!

Great idea and excellent for dull wintry days but my experience is that in sunlight the projected image is barely visible and with dark glasses is not visible at all. Excellent concept and great safety aspect but needs to be a lot brighter for all around weather.
