I have 2 Helix 12 G3Ns on my bow. One runs my Mega 360 the other runs my 2D, SI, and DI. Yesterday I hit a pretty good wake on my way to my next spot. After I got to my spot, I put the TM down and noticed that my unit that runs my 360 is on the mapping screen. I switched it to my 360 screen and a little while later noticed it was back to the mapping screen. It did this the rest of the afternoon. I am also getting the messages, 2D sonar source lost, DI sonar lost and Mega 360 source lost. I can hit my quick key and the 360 will come back on. It might run for one min, it might run for 5 mins before it switches to the mapping screen and I get the messages. Any help would be greatly appreciated.
