Is the mic in the screen part or do you have a cabled one? I have an older model (same as Shiney's) and I keep the panel in the top box with the wired mic placed on my bike's dash. It gets no wind interference there (admittedly I don't have an ST) except on the odd occasion I pull over to take a photo on a day when I have a tailwind. an you change the color of the timestamp or is that blue it? Mine is white.
