Can an external Hbd SI transducer feed SI data to a new Solix 12 CHO through a Y cable if my mega 360, also connected to the Y cable, is out of the water? Sometimes, I'll be fishing in stump infested water where I'll have the M360 stowed on the deck for safety and the transducer deployed under the TM running just above the stumps and wanting to see SI.If answer is NO, then is disconnecting M360 from Y cable all I need to do? Or do i have to fiddle with the Solix settings?Questions relate to new boat scheduled to arrive sometime next month.
