Viewing Cartography
In the Chart or Combo Views there are several cartography-related functions that you
can access using various keys.
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 bull's eye
cursor is drawn at the center of the screen and
is linked to the boat by a gray 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.
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.
