HIGH COMPATIBILITY: The HUD display connects easily via the vehicle's USB power source (such as a USB adapter for the cigar lighter). This ensures compatibility with all vehicles that provide USB power, including gasoline, derv, electric cars, and even trucks. It's a true plug and play solution.

GPS SPEEDOMETER: Utilizing GPS satellite signals for precise speed measurement, the display projects your vehicle's speed in large, clear digits onto the windshield. This allows drivers to observe their speed without glancing down at traditional dials, significantly enhancing driving safety.

AUTO BRIGHTNESS ADJUSTMENT: Built in ambient light sensor detects day and night changes, automatically enhancing brightness during the day for clarity and dimming at night to avoid glare. Provide a comfortable visual experience without manual intervention.

SPEED AND DIRECTION DISPLAY: Display speed, driving direction, auto light sensing, and switch between speed units in KM/H and MPH. Set 3 level speed alarms with flashing warning without sound. Ensure voltage does not exceed 5V.

ENHANCED SAFETY: This innovative speed gauge HUB promotes safe driving habits by keeping essential information front and center. With its clear projection and real time updates, drivers can focus more on the road.
