You can use the 

 or 

 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 ad-

vanced functions and for setting various options. (Options and setup 

are discussed in Sec. 8). To access the Navigation Page Menu, from the 

Navigation Page, press

Map Page 
The Map Page screens show your course and track from a bird's-eye 

view. By default, this unit shows the map with north always at the top 
of the screen. (This can be changed. See the topic Map Orientation, in 

Sec. 8.) If you're navigating to a waypoint, the map also shows your 

starting location, present position, course line and destination. You, 

however, don't have to navigate to a waypoint to use the map. 
Map Page is the default screen that appears when you turn on the unit. 
To get to the Map Page from another page: Press

. When the Map Page is displayed, a screen similar to the fol-

lowing figures appears. 
The arrow in the center of the screen is your present position. It points 

in the direction you're traveling. The solid line extending from the back 

of the arrow is your plot trail, or path you've taken. 
The map zoom range is the distance across the screen. This number 

shows in the lower right corner of the screen. In the first of the follow-

ing example figures, the range is 4,000 miles from the left edge of the 

map to the right edge of the map. 
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its 

coverage area and the amount of mapping detail shown. There are 39 

available map zoom ranges, from 0.02 miles to 4,000 miles.
