Downloading Charts
Many charts can be downloaded using the X-Traverse for Mac OS X application. Available here.

Opening Charts
GPSNavX™
is compatible with Softcharts and BSB charts. (Note: BSB 4 and BSB 5 charts must be registered prior to use). A world chart is included with GPSNavX™. Additional charts must be purchased separately. Copy or download the charts to your hard drive preferably to a folder in your home folder. We recommend "Charts" as the folder name.

Before charts can be opened other than the world base chart, the top level folder where the charts are located should be set in the Preferences window. On the Preferences window press the "Folder..." button. Using the Select Folder dialog choose the FOLDER where the charts (.kap or .cap or .bap or .nos/.geo files) are located. If you have more than one folder with charts then select the top level folder.

To open a chart select the menu item "Open Chart..." on the "File" menu. This will open the Chart List dialog. Scroll through the chart list and click on the chart you wish to view. Select the "Open" button or double clck to load and view the chart. The first chart in the list will be the world chart. Select the "Preview" check box to see the chart before opening. The "+" and "-" buttons can be used to zoom and the chart can be scrolled with the scroll bars or by dragging it. Select the "Folder..." button to change the top level folder where the charts are located.

The "List Charts" combobox on the Chart List dialog selects which charts are listed. Select "All" for all charts, "Position" for the charts that have the current position (either from the connected GPS or the chart), or a specific waypoint.

If the GPS panel is opened (via menu item "Connect" on the "GPS" menu ) and a current position is transmitted from the connected GPS, selecting the "Auto Open" menu item from the "File" menu will automatically load the most detailed chart for the current position. As the position changes the most detailed charts will be automatically loaded. When "Auto Open" is enabled the "Open" menu item on the "File" menu will be disabled. "Auto Open" searches using the folder and it's sub-folders set the in the Preferences window.

In the Preferences window the "Open last viewed chart at Startup" checkbox can be selected to enable GPSNavX™ to automatically open the current chart when it is started up again.

Using Charts
Once a chart is loaded there are several available operations and options. The Zoom popup menu in the Chart Settings panel and [+] and [-] keys allow the chart to be zoomed in and out. Scrollbars allow the chart to be moved around as do the arrow and page keys. The Chart window can also be resized. The "<<" button will restore the previous zoom. The "[ ^ ]" button will center the chart to the current GPS position if it exists on the currently opened chart.

[option] click anywhere on the chart to center the chart to that point.

Double click anywhere on the Chart window to zoom and pan.

The "Mode" buttons toggle the mouse action on the chart:

Select the "hand" to drag/scroll the chart. Also selected by holding down the space bar.

Select the "selection" to choose an area of the chart to zoom. Drag to create the selection.

Select the "<+>" to move waypoints. Move the cursor over any waypoint name on the chart and drag.

Select the "box" to turn to display the bounds of any intersecting charts. Double click inside the bound of any chart will load it. Double click outside the bound of any chart will load the next larger chart.

Select the "pen" to annotate the chart. The pen color can be selected with the adjacent color well. To remove an annotation [control] click on it and select "Delete" from the context menu or use the [delete] key. To remove all annotation use the "Delete All Annotations" button in the Preferences window.

Select the "line" to get a distance and bearing from a point and/or move the mouse cursor anywhere on the chart to obtain a position. If the GPS panel is opened (via menu item "Connect" menu "GPS") and a current position is transmitted from the connected GPS, that position will be used as the origin of measurement. To use a different origin hold down the [command] key before dragging. To use the selected waypoint in the Waypoint window, hold down the [option] key before dragging.

If the GPS panel is opened (via menu item "Connect" menu "GPS") and a current position is transmitted from the connected GPS, the chart will scroll with the position as long as the menu item "Position Centered" on the "View" menu is selected. The position Icon attributes such as "Color" and "Size" can be selected in the Preferences window. The "Velocity Vector" will draw a line segment in front of the position equal to the length of the selected time.

In the "View" menu the "Day", "Dusk", and "Night" menu items control the intensity the chart is displayed.

[Control] click any where on the chart displays a context menu. The "Open" menu item will open the Chart List dialog with the charts listed that have that positon. The "Open Detailed" will open the most detailed chart for the position clicked on. At the bottom of the context menu will be a list of any charts that intersect with the currently opened chart. Those that have the selected position will be displayed in a bold font.

Selecting "Mr. Tides" from the context menu will open up the Mr. Tides application to the closest station where [Control] clicked on the chart. In order for this to work the Mr. Tides application (version 3.00 or later) must be installed on your Mac in the Applications folder. Mr. Tides can be downloaded from..
