SinoTrack GPS Speedometer HUD for Car 5.5" LCD — Universal Heads-Up Display with Overspeed & Fatigue Alerts

SinoTrack Digital GPS Speedometer is a universal heads-up display (HUD) with a large 5.5" LCD that shows real-time MPH, trip data, direction, and issues audible overspeed and fatigued-driving alerts.

This compact HUD plugs into any vehicle and uses GPS to present clear, real-time driving information on a bright, auto-dimming screen. Designed for easy one-button setup and continuous operation while the car is powered, the device prioritizes visibility and safety reminders — including a configurable overspeed alarm and a fatigue-driving notification after prolonged driving. The SinoTrack HUD uses a dual-core processor for responsive updates and includes a compass, satellite count, trip meter, and automatic brightness control so data stays readable in day or night conditions.

How does the SinoTrack HUD help me drive more safely?

The unit provides two core safety prompts: configurable overspeed alerts to notify you when you exceed your chosen speed, and a fatigue-driving reminder after continuous driving to encourage a break. Alerts are audible so they capture attention without requiring you to look away from the road.

• Customizable overspeed alarm threshold with ticking sound
• Fatigue reminder after approximately four hours of continuous driving
• Large numeric speed display reduces glance time from the road
• Compass and heading help maintain situational awareness

What information is shown on the 5.5-inch display and how clear is it?

The extra-large LCD presents speed, satellite count, direction, trip distance, driving time and more simultaneously. The backlit screen adapts automatically to ambient light, and you can also manually set brightness for the clearest readout under strong sun or at night.

• 5.5" HD screen with two speed scales and satellite indicator
• Auto light-sensor adjusts brightness for day and night use
• Manual brightness control up to level 11 for maximum luminance
• Central compass and multi-field data layout for quick scanning

Will this HUD work in my car and how do I operate it?

SinoTrack is a universal GPS HUD that runs from a 5V power source and needs the vehicle’s power while operating. Setup is simple: press to enter settings, short presses cycle display modes, and a long press opens the full configuration menu.

• Universal compatibility with most cars using a 5V power supply
• One-key operation: long press for settings, short press to toggle displays
• Displays only current trip mileage (resets with power off)
• Built-in dual-core processor for smooth, real-time updates

How do I maintain brightness and avoid display issues?

The HUD uses a rear light sensor to auto-adjust brightness; keep the sensor hole unobstructed for correct automatic operation. If needed, you can increase brightness manually through the settings to ensure visibility in direct sunlight.

• Auto-sensitive brightness enabled by default for convenience
• Adjust brightness to "11" in settings for maximum output
• Avoid covering the small sensor hole on the back to prevent dimming
• Do not use chargers above 5V or fast-charging adapters to protect device life

Who is this for: SinoTrack’s 5.5" GPS HUD suits drivers who want a clear, dedicated speed and trip display without relying on the vehicle cluster or smartphone. It’s useful for long-distance commuters, drivers wanting audible overspeed reminders, and anyone who benefits from a large, auto-dimming heads-up readout. The device is also a practical gift for family or friends who spend significant time behind the wheel and value visible, immediate driving feedback.
