Installed the new transducer on my tm yesterday. Ran the updates and took the boat to the lake. The Livesight asked to be set up which was just telling it to look forward. After that just had a black screen. Found that if I disconnected the NEMA cable and Ethernet cable I got the live image. I need to see if it will still work reconnecting one cable at a time. Any ideas why it didn’t work with both cables connected?
