4. Press 

 to turn off the steering and speed boxes. The unit will now 

automatically "steer" along the trail or route. When you arrive at your 

"destination," cancel navigation as you normally do. 

You can pick any spot on the map to begin your simulation session 

by using the Initialize GPS command. This makes your unit think 

it's located at the position you select. See the following entry. 

This command is handy when you are practicing in simulator mode 
(See the entry in this section for GPS Simulator.). In simulator mode, 

this command makes the unit operate as if it is sitting someplace other 

than its actual location. So, you and your unit could be located in Kan-

sas City, but practice navigating in the ocean off Islamorada, Florida.

2. A message appears, telling you to move the cursor near the desired 

location and press 

. When the message automatically clears, follow 

the message instructions. 
3. In a moment, your present position marker arrow appears on the 

map in the location you selected with the cursor. The unit will consider 

that spot as its last known position until changed by either a live satel-

lite lock-on or a new simulator location. 

This receiver has an auto zoom feature that eliminates much of the 

button pushing that other brands of GPS receivers force you to make. It 

works in conjunction with the navigation features. 
First, start navigation to a waypoint (See the waypoint section for more 

information on navigating to a waypoint.). Then, with the auto zoom 

mode on, the unit zooms out until the entire course shows, from the 

present position to the destination waypoint. As you travel toward the 

destination, the unit automatically begins zooming in — one zoom 

range at a time — always keeping the destination on the screen.

This menu lets you turn the map off, if desired (which turns the map 

screen into a GPS plotter); turn off or on the pop-up map info boxes; 

draw the map boundaries or boxes around the areas of high detail; or 

fill land areas with gray. You can also turn on or off Map Overlays,
