This is not a different brands issue.

Anything with a NMEA connection uses that specific protocol. Inside of the NMEA 0183 protocol are a series of “sentences” that can be output to the autopilot.

For example on my boat I have A Furuno Navnet VX2 chartplotter connected to my Simard autopilot. In order for them to “talk” all I had to do is configure the NMEA port on the Furuno to output the standard stuff that autopilots need, which in my case was to turn on NMEA sentence AP1 and AP2 if memory serves correctly.

Yes complex integration between brands, things like map sharing and the like are challenging or just not possible. In the case of an autopilot there is just a little information that needs to be shared, and it is easily adressed by using the NMEA protocol suite.
