I cannot get the seatalk to function on the chartplotter 320 GPS ,I have it
connected on the Seatalk daisy chain connected to Autohelm ST 50 upgraded to
ST55 and Autohelm auto pilot. As soon as I plug in the Seatalk cable to the
input on the 320 ,the TRUE wind crashes on the wind instrument .I have
checked every connection everywhere .Could it be a configuration problem in
the setup Menu? Help
