This is a dongle that allows you to connect to the USB port of a car navigation system running Android OS, enabling CarPlay or Android Auto compatibility. Please check the following website for details: https://amzn.asia/d/g6IzMXl The website only lists compatibility up to iPhone X, but I have been able to use it with iPhone 8, 12, and 16. There is some discoloration, but I don't see any scratches. The box and instruction manual are not included, only the main unit. Thank you.
