I am experiencing various problems interfacing my NAV6 to Raymarine...

Certain Raymarine (previously Raytheon) equipment offers the facility to bridge instrument data transmitted on SeaTalk to an NMEA output. Unfortunately this bridging facility is not comprehensive in all cases, for instance a RC520 will display wind information if it is available on the SeaTalk interface, but does not bridge the wind data to its NMEA output interface.

We recommend that you carefully read the user manual for any Raymarine products that you own before connecting an NMEA output to the Nav6's NMEA input. You may find that the data that you wish to display on the NAV6 is not output by the Raymarine equipment (as in the example above).

In these cases we recommend that you purchase a Raymarine Seatalk to NMEA bridge product and use this to bridge Seatalk instrument data to the NAV6's NMEA input.
