The programmers at Honda/Harmon obviously do not know what contrast is. The color changes on the latest update, as far as I could tell only changes the color of the main roads. The black and white choice actually provides good contrast and visibility. If this was 1970, I would have been delighted with this mode. They have however increased the font size on road names for all of the selections except the yellow, which is probably the original. I also had the system freeze with a screen message that this function was not available while moving. I had hit the Home button on the handle bar when I was operating in AA. No button pushes would clear it, however after a few minutes it cleared itself and all functions again worked normally. I found switching to AA after running the onboard nav while it was routing gave me the AA screen and the voice directions from the onboard nav.
