    HD9 Gen 2 on Bow and HD7 Gen 2 at Stern, networked together.

    HD9 transducer is mounted on base of trolling motor.

    HD7 xducer is mounted in bilge.

    All works fine except Down/Side Scan on troll mounted xducer.

    When I go to menu and choose source on Down Scan to the HD7 it is clear as a bell (this is when I am looking at the HD9 on bow while trolling), when I switch source back to HD9, the screen begins scrolling blank.

    I checked the connections to the back of the HD9 unit, checked the cable tucked into the trolling motor frame, and where it is zip tied down the frame to the bottom of the trolling motor mount for any kinks/cuts. Didn't find anything.

    All I can think is maybe somehow I have damaged the pins on the connector (that runs to the xducer) into the back of the unit?

    Have run through all the menu settings etc but nothing has changed for this one issue. Any ideas?
