OK, 492/498 only has one nmea output, the other is a CAN output (nmea2000).
So the connection to the autopilot should be made with the BLUE cable of the power/data cable, this goes to the positive (+) NMEA IN terminal of the autopilot.
Depending the model that would be the back of the display (ST4000/5000 series) , the back of the
cockpit connector (in tiller pilots) or the connectors in the course computer (S1/3, Type100/300, X series, et al)
Then connect negative (shield) to the - NMEA IN as well. This should be done bridging the BLACK Garmin negative cable and sending it to the pilot, but as shield is shared all around the
boat, if for some reason this becomes difficult, I sometimes bridge NMEA IN - with the negative from 12V in the AP. should
work, but the correct way to do it is with a direct connection of both + and - between the
equipment you intend to share data.
Remember to program the Comm SubTab for NMEA IN/OUT. good luck. alex
