Chart View with Cursor Present, shown with Optional-Purchase Navionics® Cartography
Viewing Cartography
In the Chart 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 distance and bearing from the boat to the cursor position and the latitude/longitude coordinates of the cursor are displayed in the upper info boxes.
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/lon grid will be drawn instead.
Chart Info: Use the INFO key to get detailed information about the chart through the Chart Info submenu. 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 using the 4-WAY Cursor Control key.
NOTE: The built-in UniMap™ does not contain any Port, Tide or Current information. This information is only available from optional-purchase MMC/SD cards.
