[CA] [CA11] MFDs rebooting and intermittent GPS

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Mark,

Please click here to view a FAQ addressing this subject. As inferred therein, the first thing to ensure is that each MFD has been updated with the final LightHouse II software update (i.e. v19.03) and that Sonar Logging feature has been disabled. Regarding the GPS issue, as the system features more than one potential source of GPS data, it then is recommended that you verify that the Data Sources feature (HOME->SET-UP->SYSTEM SETTINGS->DATA SOURCES) has been used to specify the source of GPS data, Datum, and Date & Time. As indicated within the FAQ on this subject, should the MFD which is serving as the system's source of GPS data not have an unobstructed view of the skies overhead or should the mounting surface adversely affect GPS signal reception, then the system may need to be interfaced to an external GPS sensor (ex. Raystar 150 GPS Sensor, etc.), external passive GPS antenna (ex. GA150 GPS Antenna, etc.), or a MFD w/internal GPS sensor which in turn has been installed in a location affording an unobstructed view of the skies overhead.
