Hi all, my X50 felt on the floor of my car this weekend and i noticed that theres a little anoying sound coming out of it, i dont know if it was like that before it felt too. The sound disapears when i put the RD display in fully dark mode. I dont know if you guys X50s are doing that kind of sound? heres the audio http://www.filefarmer.com/SpeedFreak/test1.mp3 In the audio im turning it on with MAX brightness and then i switch to fully dark,min,med and max brightness. I think youll have to put the volume up a little bit to hear what im talking about. can you guys tell me what you think about this?
