P70 No pilot error and mode page blank

Bob,

Per our conversation the About System diagnostics feature of the autopilot control head should list all SeaTalkng / NMEA 2000 devices which have additionally been interfaced to the backbone ... including your C90W. Given the symptoms reported during attempts to use this feature and reported during attempts to update software within the Evolution autopilot components, it would appear that the MFD may have suffered a failure of its SeaTalkng / NMEA 2000 communications circuitry. It is accordingly recommended that the MFD be sent to Raymarine’s Product Repair Center to be bench checked / serviced. As the software within the ACU, p70R, and likely the EV-1 CCU are also not current, it is recommended that these components also be sent to Raymarine's Product Repair Center to be updated. It is further recommended that the EV-1 CCU be bench tested by Raymarine's Product Repair Center given that the autopilot had initially functioned properly before communications between the autopilot control head and EV-1 CCU ceased.
