AZIJYV H4 Heads Up Display - GPS+BDS Plug and play

【Safe Driving Smart Companion】AZIJYV W2 Automotive Heads Up Display for Cars projects key information like vehicle speed onto the front windshield, enabling a keep-your-eyes-on-the-road driving experience. Equipped with a high-precision Speedometer for real-time speed display and supporting three adjustable overspeed warning levels (60/80/120km/h), it immediately triggers visual alerts when the speed exceeds set thresholds, effectively preventing speeding risks. 【Intelligent Light Sensing & Energy-Efficient Power Supply】Built-in ambient light sensor allows the Digital Speedometer for Car display brightness to automatically optimize based on day/night lighting conditions. Utilizes a Type-C high-speed transmission interface, supports power via car USB (5V) or cigarette lighter adapter, and automatically cuts off power after the vehicle is turned off, completely eliminating battery drain issues. 【Professional Anti-Glare Optical Design】The integrated body comes with a dedicated sunshade, effectively reducing nighttime glare interference. The HUD employs a 10Hz high refresh rate dual-mode chip, combined with a data update frequency of 10 times per second, ensuring real-time, lag-free readings on the Speedometer for Car. The oversized font display makes driving information clear at a glance. 【Universal Compatibility & Plug-and-Play】This Heads Up Display is compatible with all vehicles equipped with a USB interface. Its compact size allows flexible placement anywhere on the dashboard. Features intelligent auto start-stop function—automatically activates projection when the vehicle starts and immediately enters standby mode after turning off the engine, achieving truly zero-operation intelligent management. 【Dual-Core Processor for Precise Monitoring】The Heads Up Display for Cars uses a high-performance dual-core chip to achieve millisecond-level response to speed changes. Compared to traditional mechanical gauges, this Digital Speedometer for Car can control real-time speed error within a ±1km/h range, providing professional-grade data support for users who value precise driving. 【Speed accuracy】GPS speedometer devices have a slight normal error of 0.6-1.8mph (in accordance with industry standards), so there is no need to worry. We have a built-in speed adjustment function, and you can calibrate it yourself in the settings until it matches the actual speed of the vehicle completely
