Travel Time is the time 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 figure, the driver is headed northwest (a 307º track) toward a waypoint 307º (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 002, which is 5.65 miles away. Traveling at a speed of 70 mph, the driver will arrive at the waypoint in 3 min- utes, 24 seconds.

The Navigation Page has its own menu, which is used for some ad- vanced functions and for setting various options. To access the Naviga- tion Page Menu, press MENU while on the Navigation Page.

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 are navigating to a waypoint, the map shows your start- ing location, present position, course line and destination. You 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 PAGES← → to MAPEXIT. 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 are traveling. The magenta 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 left corner of the screen. In the first of the following 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 40 available map zoom ranges, from 0.02 miles to 4,000 miles.
