I’m reposting part of this from nearly a year ago as I’ve decided to return to this headache and try to finally fix it…if possible.  I have a 2020 Mitsubishi Outlander Sport.  The digitizer on the head unit failed and I picked up a new one.  It was an easy replace since the LCD isn’t fused with the digitizer.  The wire harnesses are nearly idiot proof, so put everything back together in 10mins.  The headache started when I fired the car up on the display now show a completely mirrored image of its former function (see photo).  The digitizer virtual buttons were all in the correct place meaning if the display showed the button reversed from proper on the right, the digitizer button was on the left over nothing on the screen.  In short perfectly functioning digitizer but the images on the LCD were mirrored.  I tried all manner of things: looked for dip switches on the PCB, factory reset, soft reset, leaving the unit unplugged for a week, reversed the idiot proof ribbon cables….nothing worked.  There’s nothing in the settings menu about a mirror mode and nothing in the dealer menu either.  After reading up on faulty Chinese digitizer, I bought a new one..:this time as a complete digitizer/lcd set..no change.  Perhaps the display pcb is bad?  Maybe r/t the failed digitizer?  IDK.  I’m completely out of ideas.  Anyone know where I can buy a cheap-ish used NR-201 head unit?  I’d even be willing to buy one with a smashed screen since I have brand new one.  Otherwise, I could use some sagely advice.
