[CA] ST70 No Pilot Message

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Danny,

The symptoms reported are indicative of a failure of SeaTalkng communications between the autopilot control head and the autopilot course computer. Should these two devices be the only devices which have been interfaced to the SeaTalkng backbone and should the autopilot course computer be powered, then the problem may be rooted within SeaTalkng communications circuitry of either device or a may indicate fault within the SeaTalkng networking components. The FAQ found here may be used to determine how to test the SeaTalkng networking components of SeaTalkng / NMEA 2000 backbone. Should you need a technician to perform these services, then it would be recommended that a Certified Raymarine Installer be contacted. Should no fault be identified with the SeaTalkng networking components, then it would be recommended that both the autopilot course computer and autopilot control head be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
