Looking at helix 7 models and am finding 410 340-1 models and 410 330 -1. Some models are g2N models. I am not sure if it just designates newer model or if it is different software. Humminbird lists only the 340 model. Help going through the mine field

“N” designation means it’s a network enabled unit able to communicate with other networked equipment.
