I have had my helix 10 gen 2 into the factory 3 times, I am still having problems. I have not been able to get any sonar since January, no 2d, no si, no di...have had factory rep in boat and acknowledged the problem. I just got it back last Thursday, I am getting sonar reading finally, but am losing the left side of my side imaging. If I restart it will come back and then go away, but will not stay on. I have replaced the transducer that Humminbird sent, I also out in a new power cable and wye cable...all through my dealer install. This is driving me crazy! I just want a unit that works! I will be calling them again Monday and unless they gave a fix it is going in for the fourth time. Very frustated. See attached video...any ideas?
