The garmin chartplotter can work at 38400bps, same for the AIS transponder. Raymarine autopilot and vhf/dsc radio work only in 4800bps.
To get all the data from these devices into SK is nice and easy.
But to select which/what data is coming from chartplotter to autopilot (for Autopilot Track Mode) and what data is coming from AIS transponder and sent to charplotter (to show the AIS targets) is a very complicated task.
Have you tried the nmea-nmea app?

https://www.npmjs.com/package/nmea0183-to-nmea0183
Pick and choose what NMEA gets outputted by which serial devices.
