Review: Great supplement for cars w no digital display - Works great... my subaru is gauges only.. iy helps to have a digital display on glass driving through cop infested parts of town.
Review: Great little device but do NOT fully trust it - I purchased this in June 2024, and have installed this in three different cars. Overall it works wonderfully, but it has one flaw you should be aware of. It works great at night and 99% of the time during the day. If you’re driving towards the sun on a clear morning/evening, it can be pretty hard to read, but that’s to be expected, not much you can do about that. It’s also a little hard to read when wearing polarized sunglasses. However, this speedometer is not totally accurate. It’s an excellent driving aid, but don’t put your full trust in this. I’ve found that between 0-50mph the speed is spot on, maybe a 1-2mph variance. However, if you’re driving highway speeds, the speed often reads too high on this device. The highway near me has those radar cameras that tell you your speed as you pass by them. I’ve noticed that whenever the radar says I’m driving 72-73mph (which matches my car’s built-in speedometer), the heads up display will read 79-82mph. Not a big deal, but if you’ve got a dashcam and that incorrect, inflated number shows up on the footage, that might hurt your claim with your insurance company, depending on your circumstances. So be careful where you place it and how you use it! Otherwise, this is an awesome addition to any car old or new!

## Features

- 【 M1 hud】：M1 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】The M1's screen design 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 displays speed, with speeding alarm and fatigue warning function, GPS compass shows direction. Speed is available in MPH and KM/H units, which can be adjusted in the setting. When there is over speed or continuous driving for too long, the product will emit a beeping sound to remind the driver, which is like a safety supervisor, always remind the driver to pay attention to driving safety, placing a mini M1 HUD inside the car will definitely add a lot of fun.
- 【Automated Brightness】The product 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 product is easy to install, plug and play, just use the usb cable included inside the product to connect the car and the product, start the engine to power on and use. When you find the small icon on the product is flashing constantly, it means the product is collecting satellites, and the speed will be displayed only when the device searches for satellites.
- 【After-sales service】：Our heads up display for cars have passed two inspections by the quality inspection department before leaving the factory, all products encountered unresolved problems within one year, any questions about the product, you can directly mail us, we will provide you with better after-sales service!
- 【Note】: The reasons for the slow speed of satellite search: ① In garages, overpasses, and dense buildings, the speed of satellite search will be affected; ② When the same GPS device is installed in your car, it can also affect the search satellite speed of the product, which means that the two GPS devices cannot be placed together; ③ When there is a metal film on your car, it can also affect the search satellite speed of the product. You can drive the car to an open area and place the product outside the window for satellite search.
