I had the issue with my NAV radio where the display would randomly turn off and on and sometimes not work at all. I just installed a new display driver board behind the display screen and the display now works without issue. However, my manual buttons (map, audio, climate, etc) are now mirrored. The map (top right button) brings me to the climate screen (top left button). So the manual buttons bring me to the screen of the button opposite of it. Is it possible I put in a display driver board for a RHD model? Mine is LHD. I know the RHD radios have the buttons mirrored compared to the LHD radios.
