AZIJYV M22 Windshield HUD Speedometer - GPS Heads-Up Display, Overspeed Alarm, Plug-and-Play

The AZIJYV M22 Windshield Speedometer Projector is a plug-and-play GPS head-up display that projects your vehicle speed, direction, trip time and overspeed alerts onto the windshield for safer, eyes-on-the-road driving.

The M22 converts your windshield into a transparent instrument panel using a flat-screen HUD design tuned for windshield reflection. It runs from GPS signals, supports both km/h and mph, and includes alarms and a compass. Installation is straightforward: plug the unit into your car's USB power, allow it to acquire satellites, and the screen will automatically power with the vehicle.

How does the M22 show speed and travel data while driving?

The device uses an internal GPS receiver to calculate real-time speed and distance traveled, then projects that information onto a reflective film or the windshield itself. Speed updates are continuous once satellite lock is achieved, and you can switch units between kilometers per hour and miles per hour in settings.

• Real-time GPS-based speed readout (no wiring to vehicle ECU required)
• Displays trip time, cumulative distance and current clock
• Units selectable: km/h or mph in device settings
• Speed refreshes automatically after satellite fix

What safety features does the HUD include to prevent speeding?

M22 provides an overspeed alarm that emits an audible beep when you exceed the speed threshold you set. The alert acts as a configurable reminder to help you maintain safe speeds without glancing down at the dash.

• Customizable overspeed threshold with audible beep
• Bright numeric display to reduce driver distraction
• Automatic power on/off with engine start/stop for consistent availability

How easy is installation and daily use?

Installation is plug-and-play: connect the included USB cable to a 5V car power source and place the HUD on your dash. The unit begins collecting satellites immediately; a flashing icon indicates satellite search, and normal speed display appears after lock.

• Includes USB cable for simple connection to car power
• Place unit on dash and aim toward windshield for best reflection
• Automatic startup with engine and shutdown with power off
• Quick setup guidance for brightness and unit selection in menu

Why might satellite acquisition be slow and how can I improve it?

Signal acquisition can be affected by enclosed areas, elevated roads, dense urban canyons, metal window films, or the presence of another GPS device nearby. Moving to an open area and ensuring no other GPS unit is installed nearby speeds up satellite lock.

• Avoid garages, tunnels and multi-level structures during initial search
• Remove or relocate other GPS devices that might interfere
• Beware of metallic or heavily tinted windshield films that block signals
• If display appears dim in daylight, use included reflective film or increase brightness

Who is this for: The AZIJYV M22 HUD is aimed at drivers who want a low-effort upgrade to situational awareness—commuters, delivery drivers, or anyone who prefers keeping eyes forward rather than looking down at the instrument cluster. It suits virtually all vehicle types because it relies on GPS rather than vehicle-specific wiring, making it a universal accessory for safer, more informed driving.
