I am not familiar with the Humminbird AIS receiver, but I have three Humminbird 1197 units and an 1198 connected to AIS Transponders from two other manufacturers that permit the AIS information to be displayed on the mapping screens of the Humminbird sonar units.
You have not specified whaich model of Humminbird soanr unit you are referring to, but it would have to be a unit that supports AIS input either via network or NMEA connection.
I would guess that the Humminbird AIS receiver would support network connection to a humminbird sonar unit, but if nothing else it should has NMEA output.
