Right - nearly.
He wrote he also has wind instruments.
As far as i know, when you have the GPS data (Speed, Heading) transfered to
SeaTalk, the wind Instuments can display true wind speed and true wind
direction.
I don't have Wind instruments - but I heard it should work.


But anyway - what you need is a bridge between SeaTalk (ST60) and NMEA (
GPS). You need to buy a SeaTalk-Nmea bridge from Raymarine, or if you
would like to try a "Homemade Solution" you could check
