  • displaying a symbol for a direction of current travel and a symbol for a direction to be taken after a turn-off point relative to the direction of current travel;

    determining a distance from the vehicle to the turn-off point; and

    changing the size of the symbol for the direction of current travel relative to the size of the symbol for the direction to be taken after the turn-off point in response to the distance to the turn-off point while maintaining the same view of the symbols including changing the size and position of the symbol for the direction to be taken after the turn-off point in response to the distance to the turn-off point, and maintaining the size and position of the symbol for the direction of current travel independent of the distance to the turn-off point.
