ServiceNews Article - We have received information from the vendor (Alpine) that display panels are being replaced for cracks on the center display screen. When they review these parts, they're finding that an aftermarket screen protector had been installed and that the screen protector is cracked. So, if you have a center display that appears to have a cracked screen, confirm that it does not have an aftermarket screen protector installed. If installed, remove it, and then check if the center display screen itself is cracked.
