I've been reading all the problems that owners had with the original radios. The fix was to get a new unit with a green background and black letters. I have the navigation system. It has a green back ground with black letters.
My problem is that portions of the letters on the screen disappear. Even at night I may be able to read where I am and maybe not. Sometimes it looks great and sometimes almost solid green. I'm to the dealer tomorrow to see what they say. Anyone with the same problem?
