Universal Vehicle GPS Speedometer

The Avantalk G4S is a new 2 in 1 accessory that adds a GPS-based heads-up display to any vehicle. It uses a dual-mode GPS and BeiDou chip with a 10 Hz refresh rate to show speed in MPH or KPH, satellite time and a compass. The compact unit suits cars, motorcycles, trucks and new-energy vehicles without requiring a hard-wired connection to the vehicle electronics.

Upgrade from Factory Speedometer

This device replaces reliance on the original instrument cluster when calibration drift or tyre-size changes make the factory reading unreliable. The GPS-derived speed is referenced to satellite signals and can be calibrated to match the dashboard, while the overspeed alarm and four-hour fatigue reminder add safety functions the standard cluster lacks. The jump is worth it when you need an independent, easily transferable speed reference across multiple vehicles.

Simple Dashboard Placement

Installation consists of placing the unit on the dashboard where its adaptive brightness remains readable in direct sunlight or at night without blocking sight lines. No wiring harness or OBD connection is required, so there is no risk of CAN-bus interference. The only common issue is locating a spot with a clear sky view for fast satellite acquisition; deep-tinted windshields or metalised coatings can delay the initial lock.
