My heading and COG is off roughly 5 degrees. I have dual E120 units, both units are set for heads up. On the chart the boat is facing up but the chart is slightly angled. I tried calibrating the AP but it's not right. Does anyone know the location of the fluxgate or heading sensor location on the 48 Sundancer.
Also when the boat is not in motion the vessel icon on the screen is all over the place. I have it set with a 2/3 offset. It seems like its getting its heading from COG.
I had this problem with my 420 when I had a metal object in the helm storage box.

Looking for some advise.

Thanks,
Jon
