Thanks for all your help. I will try to pull out the fuse to reset the screen.

Brightness on other area like tachometer and airconditioning panel are fine. This problem used to be able to fix by shut down the engine then restart it, but now it's just very very dark. You can see everthing on NAV screen if you use flashlight or dome light. Have no ideas on what's going on. My car only 8 months old. Maybe it got used to the heat in the Middle East and when Temp drop down to like 14 C it just freek out.

Brightness on I-Drive screen is already at the max. So, I think that something wrong with the system not the operator.
