I recently bought a sailboat that has a Raymarine C70 Classic with ST6002 autopilot. The magnetic heading on the autopilot and MFD matches what a normal magnetic compass gives. When I display true heading on the MFD it is always the same as magnetic. In my area there should be 9 degree difference between magnetic and true. Should the MFD adjust it based on location automatically or is this something that can be adjusted manually? If manually then where?
