Hello guys. I have a 2006 s4 and my nav screen has gone out. i have doen some snooping on the interwebz and found that the b8s have this same issue but is due to exsessive interior heat and is a saftey in the screen so it doesnt get damaged. i am having the same symptoms however heat is not an issue as the screen has gone out in cold and hot temperatures. the screen itself is still kinda on but very very dim.dim to the point where it looks like its out completly. in direct sunlight i can see that the screen is still on but just barely. i havent checked the fuses but i will shortly. sometimes the screen works completly normaly then sometimes it goes dark. no noticable rhyme or reason as to when it goes dark. anyone else have this problem? any suggestions?
