AZIJYV Windshield Speedometer Projector, Digital Speedometer for Car GPS Speedometer with Speed, Overspeed, Heads Up Display for Cars Suitable for All Vehicles

【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.
