Guys I took it back to H B yesterday .. They said everything was fine with the unit . And updated it . I figured out what was wrong , I actually feel pretty stupid. I had installed the splitter cable when I put the unit on boat . H B has the in boat transducer back ordered and I didn't have one hooked up . After getting back on water after H B said unit was ok , same issue . I was thinking it had to be a transducer issue, and realized what I had done. I guess the unit was looking for both transducers and would lock up . I know it works great and the images are unreal. Thanks for all the help !
