Important Note

This device uses GPS satellite signals to measure speed. For accurate readings, always test the unit while driving in an open area with a clear sky view. Testing indoors or in a parking garage may result in no speed display due to limited satellite reception.

Color may vary slightly due to monitor settings and lighting conditions. Please allow ±1–2 cm measuring deviation due to manual measurement.

Frequently Asked Questions

Q: Is the G4S Mini GPS HUD compatible with all vehicle types?

A: Yes! The G4S Mini GPS HUD is universally compatible with cars, trucks, buses, bicycles, and scooters. Because it uses GPS satellite technology rather than an OBD port, it works with virtually any vehicle that has a USB power source.

Q: Can I switch between MPH and KMH?

A: Absolutely. The unit supports both MPH and KMH display modes, making it suitable for drivers in any country. You can easily toggle between the two units as needed.

Q: Why isn't the speed showing when I test it at home?

A: The G4S HUD relies on GPS satellite signals to calculate speed. If you're indoors, in a parking garage, or in an area with poor satellite visibility, the signal may not be strong enough to register movement. Take it for a drive outdoors for accurate speed readings.

Q: How is the G4S HUD powered?

A: It powers via the included USB cable, which can connect to your car's USB port or a USB car charger. There are no batteries to replace — simply plug in and it's ready to use.

Q: Will the display be visible in bright sunlight?

A: Yes. The G4S features a built-in sunshade hat specifically designed to shield the display from glare, ensuring the large, bold speed digits remain clearly visible even in direct sunlight.
