[TG] Raymarine Autohelm DGPS ST50 receiver stuck

[neilgreenfield]

Hi
I have a Bavaria yacht with a Raymaine st50 system running seatalk, with Depth, speed, nav/gps and autohelm

All was working well, until i tried to add a Raymarine C80 plotter. I assumed it just connected the same way as the other instruments. Yellow/red and ground wire.

Anyway, since fiddling and it's not working. So ive removed the C80, and put the wiring back how it was ( i think ). However the instruments, are now showing exactly the same long and lat, where ever i go. They seem to be receiving a signal from the receiver, but only the same LAT 50.41.84 one.

If i disconnect the Autohelm DGPS receiver, the system alarms sounds, for no GPS signal.

So, is it my wiring? or the DGPS receiver stuck? If it's the receiver, how easily can i remedy it, without converters and blah blah.. i like simple:-)

Thank you for any help
