Has anyone had their DIC and HUD display stop working. Mine works intermittently with no rhyme or reason. I took it to the dealer and they finally saw it out of order. The tech connected his laptop and could not see the system through his diagnostic equipment. He will refer the problem to tech support and returned my car to me. A few days later it starts to work. I have 69 miles on my Z51 3LT convertible. A pic below is what I see when its out of order. Any ideas??
