I suspect the old Raymarine MFDs provided GPS input to the course computer. I believe the 942 has a NMEA 0183 output so it will help the autopilot calibration and operation if you connect the NMEA output from the 942 to NMEA input on the course computer. I am not sure if the benefit will be that significant, but if it can be done easily (using the old Seatalk 1 wiring for example) it might be worth it.
