If Navionics or C-Map charting are needed, use Expedition or Expedition 4D.
Prerequisites
Windows 11 or 10 with at least 8GB memory. Windows 11 with minimum 16GB memory and Intel graphics is recommended.
Expedition is a highly multi-threaded application. CPUs with more cores will increase performance, especially for optimal routing.
Navionics
The Navionics Chart Installer is required to install Navionics chart cartridges from SD cards.
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 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.
