Expedition is a highly multi-threaded application. CPUs with more cores will increase performance, especially for optimal routing.

Navionics Chart Installer

A larger world chart is available containing satellite layer data. Extract from zip archive and copy to C:\ProgramData\Expedition\navionics\

C-Map 4D

C-MAP 4D charting requires the C-Map Maps Manager.

C-MAP MapsManager 2.30.2

The WWD303 More Free Basemaps chart download is recommended if available. We do not recommend updating this chart once installed.

C-MAP 4D charting requires OpenGL 3.0 or higher. See the graphics driver links on the resources page.

C-MAP 4D charting works best on displays smaller than 2732x2048 pixels. Please confirm Expedition4D works with your computer's graphics before purchasing 4D charts.
