When the upcoming turn is to be made from either of multiple lanes, it would be tremendously helpful to know which direction I am turning next, especially when the next turn is within a half mile. Many times if I get in the left lane to turn, I find out I have to get in the right lane to make the next turn in a few tenths of a mile. This becomes a risky change of lanes to be able to make the next turn. You could put an arrow on the screen or simply a dot in the top left or right corner of the current direction (top left of screen area). Even better would be to color code the dot to be red if the next turn is within a half mile and green if the next turn is more than a half mile.
