Don't remember seeing that icon, but will check it out. Locking the screen though makes no sense. If want to zoom out just a bit to see more of what streets i am approaching, within a few seconds my cursor is off the map and I can only see where I've been and none of what I am approaching. That is unless I take my hand off the wheel and my eyes off the road every 15 or 20 seconds to manually drag the map to my current location (or use the menu bottom right and touch "show current location"). Not exactly a "hands free" or even "eyes free" operation. Unless I'm missing something. Thank you for
