Viewing Cartography

In the Chart or Combo Views, there are several cartography-related functions that you can access
using various keys.
Chart View with Cursor Present
Chart Info: Use the INFO key to get detailed information about the chart. If the cursor is active, you
will see information about the chart objects located near the cursor. If the cursor is not active, the
Chart Info menu will appear. You can select the nearest port, the nearest tide station, or the
nearest current station to see information about any of these objects.
NOTE: The built-in UniMap™ does not contain any Port, Tide or Current information. This
information is only available from optional-purchase MMC cards.
Nearest Port: The position and services information for the nearest port to your present position
will be displayed. Press the EXIT key to remove the information box and the Bullseye Cursor will
be centered over the port position. The Cursor Information Boxes at the bottom of the display will
indicate the distance and bearing to the port from your present position.
Nearest Tide Station: Tide information for the nearest tide station to your present position will be
displayed. This includes the position of the station and the times of the high and low tides for
today's date. A tide graph is also displayed showing the rise and fall of the tides for the 24 hour
time period encompassing the date. You can change the date to look at tide information before or
after the date displayed by pressing the LEFT or RIGHT Cursor key respectively. Press the EXIT key
to remove the information box and the Bullseye Cursor will be centered over the tide station
position. The cursor information boxes at the bottom of the display will indicate the distance and
bearing to the tide station from your present position.

Panning: Use the 4-WAY Cursor keys to move the chart
around on the display in the direction of the key being
pressed. When you do this, a Bullseye Cursor is drawn
at the center of the screen and is linked to the boat by a
yellow line, even if the boat is off the screen. At the
same time, the temperature and speed boxes in the
lower left corner are replaced with the distance and
bearing from the boat to the cursor position and the
latitude/longitude coordinates of the cursor.
Zooming: Use the Plus (+) key to Zoom In and the Minus
(-) key to Zoom Out showing the cartography at different
scales. The scale is indicated on the left side of the
display. If you zoom in beyond the available chart data,
the display will go into Overzoom mode whereby the
last available chart data is amplified to reflect the scale
selected. If you zoom in so far that no cartography is
available, a lat/long grid will be drawn instead.
Nearest Current Station: Current information for the nearest current station to your present
position will be displayed. This includes the position of the station and the current changes for
today. Two graphs are also presented that show the time, direction and flow speed of the current
changes for the 24 hour time period of today's date. You can change the date to look at current
information before or after the date displayed by pressing the LEFT or RIGHT Cursor key
respectively. Press the EXIT key to remove the information box and the Bullseye Cursor will be
centered over the current station position. The Cursor Information Boxes at the bottom of the
display will indicate the distance and bearing to the current station from your present position.

Introduction to Navigation

Use the Matrix™ to establish waypoints at areas of interest and to navigate to those waypoints via
a saveable route (representing the shortest intended distance between waypoints). You can also
view and save tracks, which represent the actual path of the boat.

Waypoints, Routes and Tracks

Waypoints are stored positions that allow you to mark areas of interest or navigation points. Your
Matrix™ can store up to 750 waypoints.
