MAIMEIMI Windscreen Heads-Up Display HUD Digital Speedometer — Black, MPH Display with Compass & Overspeed/Fatigue Alarms

MAIMEIMI Windshield Heads Up Display projects live speed, travel direction and safety alarms onto your windshield so you can monitor key driving data without taking your eyes off the road. The MAIMEIMI car HUD is a plug-and-play digital speedometer that uses your vehicle's windshield as a projection screen to show MPH, travel direction (compass), overspeed alerts and a fatigue-driving reminder. Designed for any vehicle with a 5V USB power source, it combines a large, readable numeric display with an automatic brightness sensor so the readout remains visible from bright daylight through night driving.

How does the MAIMEIMI HUD keep speed visible without blocking my view?

The unit casts its data onto the windshield using a simplified layout and large numerals that sit within your line of sight but do not cover critical road views. You get crucial information instantly while maintaining situational awareness.

• Uses windshield as projection surface for heads-up visibility
• Large font speed readout for fast recognition
• Minimal on-screen elements to reduce distraction
• Non-intrusive placement preserves the driver's sightline

What navigation and alert features are included?

Besides displaying real-time speed, the HUD acts as a simple compass showing travel direction and offers two audible warnings: an overspeed alarm and a fatigue-driving reminder after extended driving. Alerts are intended to draw attention to conditions that may require a behavioral response, like slowing down or taking a break.

• Real-time GPS speed readout in MPH
• Travel direction compass indicator for orientation
• Adjustable overspeed alarm to warn when limits are exceeded
• Fatigue alarm sounds after prolonged driving sessions

How does brightness and accuracy work across day and night?

A built-in light sensor detects ambient illumination and automatically adjusts the HUD's brightness so figures remain legible in daylight and low-light conditions. If necessary, you can also fine-tune brightness or calibrate speed manually via the device settings to match actual road speed.

• Automatic brightness adjustment using light sensor
• Manual brightness control available through settings
• Option to enter calibration mode for speed fine-tuning
• Recommendations for obtaining reliable GPS signal (open sky, no duplicate GPS devices)

How do I install and power the MAIMEIMI HUD safely?

Installation is simple: place the HUD on your dash and connect it to any 5V USB power port in the vehicle. The device is designed for 5V operation only — higher voltages can damage it — and initial satellite acquisition may take a short time while the unit searches for GPS signals.

• Plug-and-play via any standard 5V USB outlet
• Wait for the satellite icon to stop flashing before normal use
• Move to an open area to speed up GPS acquisition if needed
• Avoid powering with voltages above 5V to prevent damage

Who is this for? MAIMEIMI's HUD is ideal for everyday commuters, delivery drivers, fleet operators and long-distance travelers who want a clearer, less distracting way to monitor speed and basic navigation without glancing down. If you drive a vehicle with a 5V USB output and prefer a compact, easy-to-install display that improves situational awareness and issues simple audible reminders, this HUD offers a practical, low-cost upgrade to your cockpit.
