Trailer Posted February 27, 2014 Posted February 27, 2014 What is the NMEA function used for on a Humminbird? I saw a youtube video on how to turn it on but have no idea what it is used for and after a google search all I discovered is that it stands for National Marine Electronics Association. Where's Wayne P when you need him? Quote
