• 5.5-INCH LARGE GPS SPEEDOMETER DISPLAY – The GPS speedometer features a large, easy-to-read LCD screen that displays real-time speed, driving time, trip distance, clock, satellite count, and compass direction, helping you view essential driving information at a glance.
• GPS-BASED UNIVERSAL VEHICLE COMPATIBILITY – Powered by satellite positioning instead of an OBD connection, this digital speedometer works independently from your vehicle’s electronic system. Suitable for all cars, trucks, SUVs, RVs, and other vehicles with a standard 5V USB power source.
• ADJUSTABLE OVERSPEED ALARM – Set your preferred speed limit, and the HUD speedometer will sound an alert when the vehicle exceeds the selected value. The adjustable overspeed range helps drivers stay aware of their speed on highways, city roads, and long-distance trips.
• FATIGUE DRIVING REMINDER – The built-in continuous-driving alert reminds you to take a break after the preset driving time. The reminder can be adjusted from 1 to 8 hours, making it especially useful for road trips, commuting, truck driving, and extended travel.
• AUTO-BRIGHTNESS DAY AND NIGHT DISPLAY – A built-in light sensor automatically adjusts the screen brightness according to surrounding light conditions, providing clear visibility during both daytime and nighttime driving. Manual brightness adjustment is also available for a customized viewing experience.
• RESPONSIVE REAL-TIME SPEED DATA – The high-performance processing system provides smooth, responsive GPS data and helps reduce display delay. MPH and KM/H units are selectable, and the speed calibration function allows you to fine-tune the reading when needed.
• SIMPLE ONE-BUTTON OPERATION – Use the multifunction control button to switch display modes, enter the settings menu, adjust speed and direction information, check driving time and distance, view satellite data, or turn the buzzer on and off. No complicated vehicle wiring is required.
• EASY 5V USB SETUP WITH IMPORTANT GPS NOTES – Connect the unit to a standard 5V USB power source and place it near the windshield for better satellite reception. Initial GPS positioning may take about 2 minutes in an open area. Do not use high-voltage or fast-charging adapters. Trip distance is measured during each powered driving session and does not accumulate after power is disconnected.
