Hi I am having the exact same problem. Everything works except the upper or radio display which is blank. It was intermittently coming on when the car ‘warmed’ up but now it doesn’t come on at all, however the radio, CD and climate controls and lower display all work no problems. I know it’s not the headunit as I tried 2 others from a Subaru wrecker and they all have the same problem with everything working except for the radio display. Did anyone ever figure out how to fix this problem?
