EWOJUYE Heads-Up Display GPS Speedometer MPH/KMH — Compact HUD with 10Hz Accuracy & Auto Dimming (Black)

EWOJUYE MPH/KMH Heads Up Display projects your vehicle speed onto the windshield using GPS + BeiDou for a steady, glare-resistant readout and configurable overspeed alerts. This compact heads-up display keeps drivers informed without taking eyes off the road. By combining signals from GPS and BeiDou satellites with a high 10Hz refresh rate, the unit presents large, easy-to-read digits through an anti-glare hood and reflective film. It installs in seconds via a single Type-C cable, automatically powering with the engine, and offers an auto-dimming screen plus manual adjustments so the readout matches your driving conditions and preferences.

How accurate and reliable is the speed reading?

The HUD uses dual-satellite reception (GPS and BeiDou) to reduce dropouts and deliver consistent speed data. A 10Hz refresh rate refreshes the digits fast enough to feel instantaneous, and you can fine-tune a small calibration offset if your vehicle’s speedometer reads slightly differently.

• Dual-satellite reception for steadier signals
• 10Hz refresh rate for smooth numeric updates
• Manual speed error adjustment to match vehicle instruments
• Displays in MPH or KM/H to suit regional needs

Will the display be readable at night and in bright sunlight?

Yes—the HUD includes an anti-glare hood and automatic brightness control to adapt to ambient light. At night, the hood reduces reflections and glare from high beams; during the day, the unit increases brightness so digits remain visible against bright windshields.

• Anti-glare hood blocks high-beam reflections and windshield glare
• Auto-dimming adjusts brightness between day and night
• Manual brightness fine-tuning for driver comfort
• Reflective film included to improve image clarity on darker windshields

How easy is installation and everyday use?

Installation is plug-and-play: route the included Type-C cable to a USB power source, affix the unit using the supplied sticker, and place the reflective film where directed. The device powers on automatically with the vehicle and shuts down when the engine stops, eliminating the need for extra wiring or manual switching.

• Single Type-C cable—no additional wiring required
• Auto on/off with vehicle start and shutdown
• Compact 3.42" x 2.12" x 0.56" footprint fits most dashboards
• Comes with sticker, reflective film, and user manual for quick setup

What safety features and alerts does this HUD provide?

The HUD offers a customizable triple overspeed alarm that flashes when you exceed your preset limit, helping you notice when speed needs to be reduced. It’s a visual aid only—no automatic braking or vehicle control—designed to supplement safe driving by keeping critical speed data in your line of sight.

• Triple-stage overspeed warnings with flashing alert
• Settable speed limit thresholds for personal preferences
• Large numeric display reduces the need to glance down
• No vehicle wiring changes or permanent installation required

Who is this for? EWOJUYE’s HUD is aimed at drivers who want a simple, noninvasive way to monitor speed and reduce dashboard glances—commuters, city drivers, long-distance motorists, and owners of cars, SUVs, or trucks without built-in HUDs. It suits drivers who value easy installation, clear night and day visibility, dual-satellite reliability, and the convenience of automatic power control. With compact dimensions and lightweight construction, it’s also a practical option for shared vehicles or rentals where quick removal and reinstallation are needed.
