The level you are currently on is highlighted. Once you click this button, a cross-section of the Station displays and 'SIDE' changes to 'ZOOM'. Select SIDE (lower left) for a cross-sectional view of the Station in the MFD. The SIDE and FULL buttons switch the map to cross-section and full-view modes, respectively.

Both maps have buttons that perform different map functions. The two buttons at the bottom of the MFD identify map views. As you explore, the module expands the map and the position marker moves. This displays a close-up view of the map, with your current position appearing as a red triangle. Select the 'AUTOMAP' button in either MFD. To use the map, press the appropriate Side Icon or '7' to activate or deactivate the navigation module’s compass feature. A directional indicator that adopts conventional compass directions shows which way you are going.

It records walls, doors, and other objects of interest, and is keyed to the Citadel Station’s shuttle navigational beacon. It is a radar-mapping system that records where you have been. The Navigation and Mapping Unit, or simply Nav Unit, is a hardware attachment found in System Shock.
