Speed source

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Almar22,

For the benefit of others who may be viewing this thread, some background may be found here. As indicated within the referenced FAQ, Speed source selection will not be permitted when Calibration Lock has been enabled ... you have addressed that. Have you used the Data Sources feature (MENU->SYSTEM SET-UP->DATA SOURCES) of the autopilot control head or of the a128 MFD to specify which source of GPS data will be used by the Raymarine products? If so, when underway and making way, are both the SOG and Speed data items being populated?
