3. Begin navigating along the trail/route. (If you are close enough to the 

first waypoint, the arrival alarm will usually go off as soon as naviga-

tion begins. Press 

 to clear the alarm.) When navigation starts, 

press 

↑ to increase speed to the desired setting. 

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 its entry following the en-
try for Hide GPS Features. 

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 Kansas City, 

but easily 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.
