G5 menu selection

I'm flying with aircraft that have Garmin G5 instruments installed and I must say, I like them. There is only one point that I sometimes have trouble with and that is when I need to select something from a menu. The... lets call it "cursor"... is a tiny 1 pixel cyan frame. And, this is sometimes hard to see (especially when in flight during a bit bumpy weather) ... is there a way to select the color for this? maybe to bright green or magenta or... don't know what could be easier to see... or make it a 2 or 3 pixel frame? (it could also overlap with other things on the screen I think, because during the selection process, I don't need a completely clear vision to the things behind) ... or what do others think about my problem?
