Automotive Electronics: Navigation, Dash Cams & Installation Safety
AI Summary: For products such as car navigation, dash cams, reversing cameras and tire pressure monitoring, procurement focuses on screen, chip, night vision, angle, power supply method and installation convenience. Dash cams should ensure the field of view does not obstruct driving, with concealed wiring and a compliant power supply. Added devices should not damage the original vehicle wiring harness, avoiding impact on airbags and warranty.
