Was adjusting the radio on the list due to lack of brightness?? I think the point is anything can be a distraction, but not having a bright enough display is NOT a safety issue. I know I don't look at my radio, I just push the buttons, because I know where the stations are set.
Not arguing, totally agree they should fix the issue--my only point is that it's not a "safety" issue, it's a stupidity issue on their behalf for even putting in a radio that no one can see in the day time.
