Hello friends ,,Have the same issue I think. Two days ago, got the car at service for rear bumper replacement. It is RX300 MY 2004 - It had the lines on the dislay, after that get "SYSTEM NOT READY" not showing them anymore. Once in the service menu, I can calibrate the steering lines etc and do checks on the camera, but get an error "5C-42" . The guy at the workshop, has no clue of the potential issue, the answer was" your model is too old to have the lines option" 😄 😄 😄 while he should be the guru in the area of Sofia...so I am here searching for options to check. So I do enter the service menu, doing all settings with the calibration - left - right - center of the steering, but I am not sure if there is any need to Save the settings and if @Yes@ - how. No clue how to exit the service menu diferent than just turn off the dashboard. Any help is welcome Thanks for your time
