I just picked up my 200 and have discovered that some fields don't seem to play nice with the color settings. For example I have REC and GPS side-by-side on the bottom row; REC is set to Black text on Red background, and GPS is set to Black text on Orange background. REC looks fine, but all I see for the GPS indicator is an orange rectangle (no text).
Same for my three avoid indicators - I made them the reverse of my sys/dept/channel colors (so if system was yellow text on black BG, sys avoid is black text on yellow BG) and all I get is the reverse-colored rectangles, no text.
I suspect it's all learning curve related...
