About this item

• 【Accurate Real-Time Data Display for Safer Driving】 This HUD GPS Speedometer projects key driving data directly onto the windshield, enabling glance-and-go access without diverting your eyes from the road. It shows a digital compass (N/S/E/W), switchable real-time speed (KM/H or MPH), driving duration (MIN), and trip mileage (TRIP). The integrated multi-function display area centralizes all critical information, effectively boosting driving safety.
• 【Intelligent Safety Alerts for Risk Prevention】 Equipped with two core safety functions, the device helps avoid common driving hazards: an adjustable overspeed alarm (ranging from 0–250 KM/H, default 150 KM/H) that warns you of speed limit violations, and a fatigue driving reminder (1.0–8.0 hours, default 8.0 hours) to prevent drowsy driving. You can personalize its use by turning the alarm buzzer on or off with a 2-second long press.
• 【Simple Setup and Customizable Settings】 The device features user-friendly operation: long-press the M key for 2 seconds to enter setup mode, then short-press to switch between 7 settings including speed fine-tuning, alarm configuration, and brightness adjustment. Brightness can be set to level 0 (automatic photosensitive mode) or manually adjusted from levels 1–11, and factory data reset can also be completed in just minutes.
• 【Reliable GPS Satellite Connection】 After power-on, the compass icon flashes while searching for satellites and stays steady once connected and ready for use. For optimal signal reception, it is recommended to use the device in open areas and avoid obstructed locations such as underground parking lots, tunnels, or bridges. When the vehicle speed exceeds 5 KM/H, the compass accurately displays the driving direction, eliminating incorrect direction readings.
• Safe 5V Power Supply & Durable Design: Operates on 5V power only—never use a higher voltage to avoid damage. Powered via USB (check cable for damage if no display);Troubleshoot in seconds: No speed display? Move to an open road for satellite connection. Inaccurate speed? Verify KM/H/MPH unit (setting 5) or fine-tune parameters (e.g., dashboard 100 KM/H vs. HUD 105 KM/H = set to 102). Time out of sync? Adjust time zone without satellites, or sync with local time once connected
