Topic: 798 CI SI GPS to VHF connection

[Suribachi]

I am trying to find out what cable I need to connect my vhf radio to the 798 head unit for GPS location transmit in an emergency. Which Humminbird cable do I need to buy. My radio has the two wire lead for this connection/operation. Does this Humminbird cable go into the comm port connection slot on the head unit's mount?

Thanks
