NMEA input to a78 MFD

I have a VHF that has an AIS receiver and I'm trying to figure out if there is a way to input that information to my a78 MFD. The a78 manual seems to tell me I can send NMEA data to my radio with a SeaTalk to NMEA converter but can not find info for how to receive NMEA output from an external source.

Does my MFD not have that capability?
