Digital OBD2 + GPS Car HUD Speedometer with Alarms

Stay Informed Without Taking Your Eyes Off the Road

The Digital Head-Up Display (HUD) OBD2 + GPS Smart Gauge projects essential driving data directly into your line of sight, helping you monitor speed, RPM, turbo boost, and key engine parameters while keeping your focus on the road. Designed for both cars and trucks, it combines OBD2 diagnostics with GPS data to deliver accurate, real-time information in a clear, easy-to-read 3-inch display.

This HUD connects to your vehicle's OBD2 port to access live engine and driving data, including speed, RPM, coolant or oil temperature, voltage, fuel consumption, simple mileage, driving time, air-fuel ratio, turbine (turbo) pressure, acceleration and brake tests, and more. In GPS mode, it can display speed, voltage, driving time, altitude, number of satellites, direction, and simple mileage, making it suitable even for vehicles that are not OBD2-compatible. Both OBD2 and GPS information can be shown on the same interface, and units can be switched between miles/kilometers and PSI/Bar/100KPA to match your preferences.

The color-changing LED interface provides at-a-glance status: blue lighting for normal driving and red flashing for alarms. You can set speed and RPM thresholds to trigger visual and audible alerts, helping you avoid overspeeding or excessive engine load. Time can be displayed in the lower right corner, and you can customize small icons and choose from nine display modes to prioritize the data that matters most to you. The upgraded system supports a wide range of OBD2 protocols, improving compatibility with most modern vehicles, while GPS mode works across virtually all cars and trucks.

Installation is straightforward: connect the OBD cable to your vehicle's diagnostic port, power on the unit, let it complete its self-test, and then fix it in your preferred position using the included double-sided tape or suction cup bracket. The interface is designed to be intuitive, making it easy to read and operate even on long journeys.
