I need some help please. I have a G2n Helix 10 Chirp SI GPS unit on the console. It worked great. I installed the recent software update and it started intermitantly losing SI, DI, and 2D and depth, especially when I put the big motor in gear. Then at some point it will begin working again. Then go blank again. The mapping or other functions never go out. I have called customer support. they have been very nice, but the only they they can say is find another unit and try it on your boat or your unit on the other boat and see if it works. So I bought a G2n 2d unit (to ultimately add for mapping only). I plugged it in and it does the same thing. I asked customer support if that means it is a transducer issue. They said no, but had no explanation. So anyone have any ideas?
Thanks in advance.
