AZIJYV M22 Windscreen Speedometer Projector — GPS Heads-Up Display, Overspeed Alarm, Auto USB Power

AZIJYV M22 is a GPS-based windshield heads-up display that projects real-time speed, distance, time and direction onto your car's windscreen for safer, non-distracting driving.

The AZIJYV M22 windshield speedometer projector is a compact HUD designed to reuse your windshield as a display surface. Powered by GPS, it shows current speed (km/h or mph), travel time, distance and a compass, plus an adjustable overspeed alarm. The unit is plug-and-play via the included USB cable, automatically powering on with the engine and switching off when the vehicle is turned off. Its simple color scheme, clear numerals and automated operation aim to reduce the need to glance down at the dash, keeping your attention on the road.

How does the M22 present speed and other driving data?

The M22 projects large, easy-to-read speed numbers onto a flat screen that reflects on the windshield, along with smaller readouts for clock, trip time and distance. You can toggle between kilometers per hour and miles per hour in the settings. If satellites are not yet locked, the unit will flash an icon until it begins receiving GPS data.

• Real-time speed readout in km/h or mph
• Displays clock, trip time and distance traveled
• GPS compass for basic direction once satellites lock
• Satellite-search indicator when starting up

Will the overspeed alarm and automatic power on/off work reliably?

The M22 includes an adjustable overspeed alert that emits a beeping sound when you exceed a set limit, serving as a driving reminder rather than a strict enforcement tool. The device powers on automatically when the vehicle provides USB power and shuts down with the ignition, reducing manual handling. For long storage periods, remove and store the unit to avoid battery drain.

• Customizable overspeed warning with audible beep
• Auto start/stop tied to vehicle USB power
• Plug-and-play USB connection—no complicated wiring
• Recommend removal if unused for more than a week

What installation and setup steps are required?

Installation is intentionally simple: plug the M22 into a USB power source, place the unit on the dash where it can reflect onto the windshield, and start the engine. Wait for the satellite icon to stop flashing to confirm GPS lock. If signal acquisition is slow, move to an open area to help the device locate satellites faster.

• Connect with included USB cable to car power
• Position on dash for clear windshield reflection
• Allow time for GPS satellite lock before first use
• Avoid installing next to other GPS devices or under heavy metal-tinted windows

How do I troubleshoot accuracy or visibility issues?

Speed discrepancies can often be corrected by switching units between KM and MPH or fine-tuning the speed offset in settings. Daytime reflections may reduce contrast; applying a dedicated reflective film where the projector displays or adjusting brightness manually can help. Keep in mind tunnels, overpasses and parking garages can temporarily block satellite reception.

• Check and set correct speed unit (KM/MPH)
• Adjust vehicle speed offset if readings differ from dash
• Use reflective film or change brightness to improve daytime visibility
• Avoid locations that block GPS signals (garages, dense buildings)

Who is this for: The AZIJYV M22 HUD is aimed at drivers who want a simple, cost-effective heads-up display to reduce dashboard glances and get immediate speed feedback. It suits personal cars, commercial vehicles and older models lacking modern HUDs, as long as the driver can provide a USB power source and position the unit so it can see the open sky for GPS lock. If you need a hardwired OEM integration or certified enforcement device, consider professional installation or automotive-grade solutions; if you want an easy, portable HUD for everyday driving and speed awareness, the M22 is a practical choice.
