I’m having an issue with my tzt3 seeing the radar sensor on the mdf. I had the pigtail replaced over the winter by Furuno after I bent and broke a pin off . After reinstalling the unit my mfd doesn’t see it. Several conversations with Furuno this week I was told to remove the rear cover on the unit and there’s an rj45 plug there where I can plug an Ethernet cable in and go directly to the mfd for testing purposes . Has anyone ever done this cause I can’t find this plug. Maybe I can get a little help or I have to wait till Monday
