I had some burnt out pixels on my old NAV screen so I ordered a replacement. Being the first time it took me about 2.5 hours to replace the screen. I installed it back in the car and the screen is off centered to the right. Looking at the old screen there are adjustment screws on the back but you have to disassemble the entire thing again and there is no way to center it when it's in pieces. Is there a way to center a stock navigation unit in the car?
