Can anyone help? I bought and installed this unit in January, it has started glitching on the screen and going completely black. I was able to cut the car off and turn it back on and the screen would come backk on but that no longer works, screen just stays black with the backlight on. Can still hear the audio and touch tone buttons on the screen but the display is black, also tried to reset with thee pinhole and screen is still black, any help? Kinda disappointed to be going through this as I’ve only had it less than 2 months. Any replies would be greatly appreciated!
