Oh right...all I can suggest now then is to get google lens on your phone & point it at the unit to translate everything & just go through the menus until you find the right settings. Mine was in with the volume controls but it was a button on the screen that found it eventually. It's a bit tedious but eventually you should find everything. I changed the screen colour, brightness, contrast...chinese chattering lady...found record & delete settings for the hard drive, camera settings, lane settings & everything. It was a combination of touch screen, physical buttons & the drive mode on the steering wheel. Hope that helps.
