If I read this right you have the adapter cable. Go into your set up menu and select generic 83/200 for the transducer, IIRC. Check the network sonar settings and make sure ti's set to the unit you have on the bow.

I've got a hds 10 gen 1 at counsole with lss1 transducer and sonar transducer mounted on Stern.
I just bought a hds 7 gen 2 for bow. I'm wanting to Ethernet it from console for structure scan off stern lss1 but use my us2 sonar on power drive v2 when deployed.
Is lowrance transducer mounted to tm better than built in us2?
I use the US2 in my Fortrex along with a LSS-1 on it. I have interference from the TM but can live with it after installing the HB choke. It seems some people have more interference problems than others, you have to try it to see. I can see a 1/16oz jig with the US2 so they work well, the Lowrance may get rid of or lessen interference though.
The vertical lines are in the 2D are interference, you can also see it in the downscan. The clear section in the center of the downscan side is when the tm was off.
