My 1198 unit had 2 wires to hook up to radio. New solix 10 nmea 0183 cable has several. Radio instructions say NMEA out negative to black radio wire and nmea out positive to red radio wire. I called humminbird tech service and it appears they readily didn't know how to make connections and referred me to nmea cable install instructions. After some discussions I was told to connect nmea orange wire (transmit a+) to radio red wire and blue (transmit b-) to radio black wire.
Unfortunately, it didn't work. Any suggestions please.
