In the example above, the driver is headed north (a 355º track) toward
a waypoint 355º (bearing) away. The cross track error range (white cor-
ridor) is 0.20 miles either side of the course. The driver is headed to-
ward trail waypoint 4, which is 0.14 miles away. The vehicle is virtu-
ally on course (off course 1 foot to the right). Traveling at a speed of 27
mph, the driver will arrive at the waypoint in 19 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. 5.). To access the Navigation Page Menu, from the
Navigation Page, press
MENU.
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. 5.). If you're navigating to a waypoint, the map also shows your
starting location, present position, course line and destination. You
don't have to navigate to a waypoint, however, 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
PAGES| → or ← to
MAP|EXIT. 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 example below, 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 enlarge or reduce the map's coverage
area and the amount of mapping detail shown. There are 37 available
map zoom ranges, from 0.05 miles to 4,000 miles.
