Need some help.  Have a Garmin CV52HW transducer mounted on my trolling motor.  Run it thru a GPSMAP 7610.  When the trolling motor is stored on the deck, my graph recognizes the transducer, but when I deploy it, it loses the connection and reverts to transmitting from the built in transducer in my Ultrex.  I get a lost connection message on the graph when I deploy it.  Anyone have any thoughts on what the issue might be?  I'm thinking a bad cable???  Thanks in advance for your help..

I can't remember where but somewhere in 'setup' you can tell it which transducer to use as a default transducer.
