You may also hold the IN or OUT keys down to quickly scroll through the map scales. The Map
Page should now display five waypoints chained together in a simple route, with your boat at the first

A data field at the top of the page now displays the speed, distance to the second route waypoint,
and a compass ribbon which shows you which way to go. To get started, let’s enter a speed for our
vessel, which we can do from the Main Menu Page.
To enter a boat speed:
1. Press the
MENU
key twice to display the Main Menu Page.
2. Use the ARROW KEYPAD to highlight the ‘Setup’ tab, then press RIGHT then DOWN until the field
below the word ‘Speed’ is highlighted on the ‘System’ submenu tab and press ENTER .
3. Use the ARROW KEYPAD to enter a speed of 40 knots.
4. Press
ENTER
to finish, and
PAGE
until you return to the Map Page.
Once a speed has been entered, you’ll notice that the map automatically begins to move slowly,
keeping your boat centered on the display. The direction of movement, also called ‘track’, is controlled
by the simulator.
The Set Position, Track Control, Track
and Speed fields only show while in
simulator mode.
You can also Invert a route to
follow it in reverse.
