1. Introdución
The VJOYCAR R1 is a universal 3D Head-Up Display (HUD) GPS speedometer designed to enhance driving safety by projecting essential vehicle data directly into your line of sight. Unlike traditional HUDs, the R1 features a 3D reflection display, eliminating the need for windshield film and preventing double images, even under direct sunlight. It operates by collecting data such as speed, trip time, trip distance, satellite quantity, and altitude directly from GPS satellites, ensuring compatibility with all vehicle types, including electric, diesel, hybrid, LPG, trucks, buses, SUVs, and ATVs.
This device connects via a standard USB cable, drawing power from your car's USB port or a car adapter. Its design ensures no interference with your vehicle's engine or computer systems.

4.2 Funcións de alarma
The HUD includes two primary alarm functions to enhance driving safety:
- Alarma de exceso de velocidade: This alarm can be configured for a single speed threshold or multiple levels (e.g., 60-100-120-180 MPH/KM/H). Each value can be individually enabled or disabled.
- Alarma de fatiga de condución: This alarm activates after a set duration of continuous driving (e.g., every 4 hours) to remind the driver to take a break.

6 Solución de problemas
If you encounter issues with your VJOYCAR R1 HUD, refer to the following common problems and solutions:
| Problema | Causa posible | Solución |
|---|---|---|
| Sen pantalla/a unidade non se acende | Sen fonte de alimentación ou conexión defectuosa. | Ensure the USB cable is securely connected to both the HUD and a functional 5V USB power source in the vehicle. Check if the vehicle's USB port or adapter is working. |
| Lectura de velocidade incorrecta | Initial GPS signal acquisition delay or calibration needed. | Allow a few moments for the device to acquire a stable GPS signal after powering on. If the inaccuracy persists, contact VJOYCAR customer support for assistance with calibration. |
| No GPS signal / Speedometer useless | Obstruction of GPS signals (e.g., tunnels, parking garages, dense urban areas with tall buildings). | This is a limitation of GPS-based devices. The signal will return once the device has a clear view of the sky. Consider this characteristic when driving in areas prone to signal loss. |
| Display is dim or difficult to read | Brightness settings or extreme ambient light. | The device typically adjusts brightness automatically. Ensure no objects are blocking the light sensor (if present). In very bright direct sunlight, some dimming may occur, but the 3D reflection display is designed to minimize this. |
| Unit does not turn off with engine | Constant power supply from the vehicle's USB port. | Some vehicle USB ports remain powered even when the engine is off. If this occurs, manually unplug the device or use a USB port that powers down with the ignition. |
