I am an infiniti driver from Turkey. I drive a 2005coupe and there are only other 3 other coupes around here in Istanbul. I have a problem and since Infiniti is not much known around here I cannot solve it because there are no official Infiniti providers nor service maintaining places. My navigation screen usually do not come out. In other words it goes up and down again even if I push the tilt button. Its going up and down immediately when I try to tilt it shows that there is not a problem in the tilt mechanism. I tilts down itself, considering that there is an electronical problem or using mistake. When I mess up with, tur on and off, and keep trying, it sometimes goes up and stays so that the screen lights up and works like any problem did not have happened anytime before. How can I solve this problem where can I mail and ask for help???
