Fluxgate compass calibration

I installed a new raymarine x5 wheel pilot with the included fluxgate compass, and the pilot is tied through nema to my garmin plotter. Everything works and the pilot does hold a true course but the boat icon displayed on the plotter does not move in the direction it is pointed.
If I set a way point at a marker 1 mile away, the boat will go directly at the mark but the icon and the line that projects from the icon showing heading shows that I will miss the mark by a substatinal amount.
When the pilot is powered down it works normaly.
The pilot display shows the same compass heading that I am seeing on my gps and is close to ( 5-10 degrees) to what I see on the real compass.
I have tried moving the flux gate and there was no change. There is a adjust heading setting for the poilt but i have moved it 20 Degrees in either direction and have not noticed any change. Any ideas?
Thanks
brad

Re: Fluxgate compass calibration

Sorry to ask the obvious, but have you gone through the full commissioning process for the new pilot? Particularly; swung the compass and aligned the compass to the boat

Re: Fluxgate compass calibration

follow the commissiing instructions for the pilot ( and hence the compass). That should sort it.

Re: Fluxgate compass calibration

I did swing the compass twice and do the auto learn, The deviation came back at 4 degress both times. As for alinging the compass my autopilot shows the same heading as the plotter, but thinking about it the plotter is likely gettting a heading from the fluxgate.

Re: Fluxgate compass calibration

A 4 degree deviation is a good number, so there must be a an issue with the integration with the plotter. Raymarine has a cople of FAQs on this very subject that may be helpful.
