Welcome to the Raymarine Forum bigskyrad,

With respect to adding AIS features to the system, its is recommended that an AIS transceiver having a SeaTalkng / NMEA 2000 communications interface (ex. AIS650) be added to the system, as is would not only support AIS features on the a125 MFD, but also on the i70 MFID. Regarding the autopilot, it is quite possible that the autopilot may be interfaced to system. However, the interfacing protocol used (NMEA 0183 or SeaTalkng) would depend upon the model of autopilot course computer installed onboard ... the ST6000 is the autopilot's control head. If supplied with the model of autopilot course computer installed onboard, then further recommendations may be provided.
