Navigation Page going to a waypoint.
The cross track error range is shown on the compass rose as a wide,
white, corridor enclosing the course line. The outer edges of this white
corridor represent lines that show the current cross track error range.
The default for the cross track error range is 0.20 miles.
For example, if the present position symbol touches the right cross
track error line, then you are 0.20 miles to the right of the desired
course. You need to steer left to return to the desired course. You can
use the
ZIN or ZOUT keys to change the cross track error range.
A circular symbol showing your destination (waypoint) appears on the
screen as you approach the waypoint, as shown on the screen in the
preceding figure.
Travel Time is the time that it will take to reach your destination at
your present closing speed. (You can also customize the time data box
to show Arrival Time instead. Arrival Time is the local time it will be
when you arrive at the destination, based upon your present closing
speed and track.)
In the preceding example, the driver is headed west (a 265º track) to-
ward a waypoint 265º (bearing) away. The cross track error range
(white corridor) is 0.20 miles either side of the course. The driver is
headed toward trail waypoint 4, which is 0.3 miles away. The vehicle is
right on course. Traveling at a speed of 8 mph, the driver will arrive at
the waypoint in 2 minutes, 17 seconds. The Navigation Page has its
own menu, which is used for some advanced functions and for setting
