Icons and symbols

Does anyone know where you can find a comprehensive listing of the icons and symbols that appear on the nav system and in the message centre? For instance, when I'm in grsss/gravel/snow mode, my screen shows an outline of the vehicle with the two front wheels alternating between blue and black. Or when I enter a route on the nav system, there are other symbols like leaves on the display. I can guess what they are, but I'm hoping there is a full list of display explanations somewhere, since they aren't explained in the owner's manual. Has anyone got a list?
