Raymarine auto pilot and seatalk

[Blackfeather]

Got a Raymarine C120 set up with Seatalk etc. Since having the Radome repaired the autopilot is about 80 degrees out from the GPS. It is showing a heading which bears no relation to the true GPS heading so if you want to head 90 degrees you have to set it at 10 degress.

On the main screen the boat's heading off to the left when the course is 'head up'

I've tried to reset to factory setings but it hasn't helped.

Any ideas?

You need to align heading in the autopilot menu.
