I have a E97 MFD and a new B744v transducer. Originally I had hooked up the 2 items when the E97 had old software V12 I believe. I was only able to get a depth reading, not speed or temp when bench tested. I then upgraded the software to the latest. V16. last week. Now I get intermittent depth, no temp or speed. And in the fish finder screen I get a message saying selected sonar not found. Then that goes away I get depth for a few seconds then message pops up. Please advise. Thanks Scott
