[CA] No Navigation Data message

[Chuck - Raymarine - Moderator]

Steve,

Please review my initial response regarding the requirements to command the autopilot into Track mode. After commanding navigation via the interfaced GPS/chartplotter, the autopilot will first be commanded into Auto mode. The autopilot may then be commanded into Track mode if the autopilot is receiving navigational data from the GPS/chartplotter. Detailed instructions for commanding the Autopilot into Track mode may be found within Chapter 9.4 Track mode of the p70/p70R Pilot Controller Installation and Operation Instructions. As indicated within the prior response, should the autopilot not sense that it has received navigational data from the GPS/chartplotter, then it will report No Navigation Data. When interfacing the other components back into your system, it is recommended that you first begin with the GPS/chartplotter and then verify that you can command the autopilot into track mode after commanding navigation (Go To Waypoint/Cursor Position or Follow Route). After proving successful operation, new third party components may be added one by one to the system and the system should once again be tested to verify that the autopilot can enter Track mode.
