As far as I know if you have AWS and AWA you only need boat speed through the water to get TWS and TWA which is shown by True on the i60 wind.
If you want to display the magnetic angle from where the wind is coming from, such as on an old ST50 multidisplay, then you need boat heading which comes from the fluxgate compass ( usually connected to the Autohelm ).

I was referring to the true wind display on a Raymatine i60 Wind. Raymarine Tech online says it needs a source of heading (and speed through the water which it gets from the i50 Speed already installed) to be able to display true wind? What are possible sources for heading? Can my old Simrad/Robertson Autopilot provide that info to the i60 with some sort of NMEA 0183 to SeaTalkng converter? Ken H.
