Adding a C95MFD to Garmin GNX20 Instruments

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Don,

Per the Garmin GNX instruments documentation, these devices have NMEA 2000 communications interfaces. Accordingly, the currently installed NMEA 2000 backbone may be extended using Raymarine SeaTalkng/NMEA 2000 networking components or Garmin NMEA 2000 networking components to create additional spur sockets to support the installation of an a/c/e/eS/gS-Series MFD and an Evolution autopilot. Should you opt to extend the Garmin NMEA 2000 backbone using Garmin NMEA 2000 netowrking components, then you may use the A06075 / 39.4in (1.0m) DeviceNet (F) to SeaTalkng Spur Adapte or A06076 / 39.4in (1.0m) DeviceNet (M) to SeaTalkng Spur Adapter. Should only these two additional Raymarine products be installed, then the backbone extension will need to include four additional spur Ts (three for the Evolution autopilot components and one for the MFD).
