Etokfoks Windshield Heads Up Display Digital GPS Speedometer Compass Alarms Automatic Brightness 5V USB for Suitable Vehicles

This windshield heads up display projects real time speed data onto the glass while keeping the driver view clear, providing a digital speedometer format that supports monitoring during vehicle use without requiring the driver to lower their head

The unit functions as a digital speedometer and simple car compass, with speeding and fatigue driving alarms that provide additional driving information through the windshield display for suitable vehicles using the available USB power connection

A built in light sensor automatically adjusts display brightness for clear viewing during day or night use, while the manual adjustment option lets the driver fine tune the screen when surrounding light conditions change during vehicle operation

The display operates at 5V through a USB connection and works with vehicles that have a suitable USB power supply, providing a straightforward connection method for drivers who need the windshield unit available during routine travel

Clear satellite reception is required for accurate speed display, so the unit may need fine tuning through its settings and careful placement when the vehicle environment or surrounding conditions affect the quality of received positioning signals

Signal searching can be affected by other GPS devices, and adjusting the placement or settings can help support best performance while the windshield display provides speed, compass, alarm, and brightness functions for suitable vehicle use
