1. Read the fault information through the car OBD interface, which can detect 10000+ fault codes of the vehicle and display them in text. After the vehicle fault is eliminated, the fault information can be cleared.2. Built-in GPS+Beidou and Galileo chip modules, can receive 32 satellites, high-precision altitude, time, latitude and longitude and other information.3. Split bracket, the bracket can rotate 360 degrees in all directions.4. Using high-temperature resistant imaging components, COB packaging constitutes an integrated light surface source, and the light-emitting surface dissipates heat evenly, which is highly efficient and energy-saving.5. Simplified Chinese, Traditional Chinese, and English function settings, switch at will.5.
