How to Extend a Route on the Screen

You can extend a route from the last point on the route. This is useful when you want
to travel beyond the last point in a route.
1. Put the cursor on any leg of the route then press the ENT key.
2. Select [EXTEND] from the context-sensitive menu then press the ENT key.
3. Drag the cursor to where you want to extend the route. A dashed line runs be-
tween the last point and the cursor.
4. Press the ENT key. The dashed line is replaced with a solid line and the point is
numbered with the next sequential point number of the route.
