Thank you for your clear and detailed presentation. The one detail that we needed was how to manoeuvre the red yellow and green reversing lines. Because you already had a reversing camera in your vehicle you did not need this function, but because you are reviewing the Lingdu LD05, you might like to add in this section, which we found in another video online. What had us tricked initially was finding how to get to English from the Chinese screen, but we kept pressing the Chinese characters on screen until we found languages.
