Although I'm a newbie been reading the post for sometime, especially before I purchased my 798c Si which I love, only used it a couple of times freshwater. A week ago before I purchased the interlink I call Humminbird, I specifically ask if the 798c Si and 955c would interlink. I told the lady I had updated both units with the latest software versions 5.45 and 4.95, respectively. Tried to install today and 798 unit says it is not compatible with the version that is on the 955c.
Any suggestions! I really do not want to call Humminbird back.
Thanks for your help! I can't wait to contribute to the site when I learn more!
