I ended up having to reposition the compass unit on the forward part of the moulded cockpit steering seat position Perhaps I missed a possible procedure but I did search the menu structure - which may have changed by now. I thought this strange, a fluxgate compass delivers a digital value, feeding a processor - a simple algorithm could be incorporated. Realising that the documentation showed all the proposed mounting positions as being on forward-facing, vertical surfaces, I confidently expected the extensive calibration options would allow a 180 degree (modulo 360) adjustment but no, the multiple possibilities did not cover that contingency. However, when the system was first switched on and the Controller display activated, I was surprised to see the ship's reciprocal bearing showing on the Standby course. Three years ago I fitted the Raymarine S1 Autopilot that included a Raymarine fluxgate compass in the kit, which I fitted facing aft on the main bulkhead next to the autopilot computer.
