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 

 or 

 keys to change the cross track error range. 

A circular symbol depicting 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 figure, the driver is headed west (a 265º 

track) toward 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.
