EWOJUYE Heads-Up Display HUD Speedometer MPH/KMH — GPS+BeiDou Accuracy, Auto-Dimming & Overspeed Alerts

This compact heads-up display (3.42" × 2.12" × 0.56") gives drivers a clear, real-time speed readout without glancing down at the dash. Built from durable PC+ABS and weighing only 3.6 ounces, the EWOJUYE HUD pairs dual-satellite reception and a 10Hz refresh rate to maintain a stable, lag-free digital speed projection. It includes an anti-glare hood and reflective film for crisp visibility day or night, plus a Type-C cable for straightforward, no-wiring installation.

How accurate and stable is the speed reading on busy roads?

The EWOJUYE HUD receives signals from both GPS and BeiDou satellites to increase signal availability and steadiness, reducing momentary dropouts in urban canyons or open highways. A 10Hz refresh rate keeps the displayed digits smooth and responsive so you can trust the readout during acceleration or deceleration.

• Dual-satellite reception: GPS + BeiDou for stronger coverage
• 10Hz update: smooth, near-real-time speed changes
• Manual error fine-tuning: correct minor speed deviations

Will I be able to read the display during day and night driving?

Yes — the HUD automatically adjusts brightness based on ambient light and includes an anti-glare hood to block high-beam reflections at night. If you prefer, you can manually set brightness to match your cabin lighting for maximum comfort and visibility.

• Auto-dimming sensor for day/night adaptation
• Anti-glare hood and reflective film reduce glare
• Manual brightness control for personal comfort

How does the alarm and unit operation work while driving?

Set a custom speed limit, and the HUD will flash a triple overspeed warning when you exceed that threshold to help you notice speed changes without checking your dash. The unit powers via the included Type-C cable and turns on with the vehicle, then shuts off automatically with the engine — no extra switches or complicated wiring required.

• Triple overspeed alarm: visual flashing warning when limit exceeded
• KM/H and MPH toggle for regional preference
• Type-C plug-and-play: auto on/off with vehicle power

What comes in the box and how easy is installation?

The package contains the HUD, a Type-C USB cable, adhesive sticker, reflective film, and an English manual for setup. Installation is simple: mount the HUD on the dash with the sticker, attach the reflective film to the windshield, and plug the cable into a USB power source — ready to go in minutes.

• Included accessories: Type-C cable, sticker, reflective film, manual
• Quick setup: stick, place, and plug; no hardwiring needed
• Compact footprint: unobtrusive size fits most dashboards

Who this is for: Drivers who want a low-friction way to monitor speed without taking their eyes off the road — urban commuters, long-distance drivers, and owners of cars, SUVs, or trucks who prefer a simple, portable HUD. It suits users who value reliable satellite reception, easy installation, and an adjustable, readable display for both daytime and nighttime driving.
