As the title says I have an issue with the sonar cable on my simrad unit. Problem is with the connecter and keeping it secured to the unit. It seems as if the little tabs that keep it in place have worn down and I can no longer screw the connector on as before. The picture kinda shows what I’m talking about. Any suggestions to what I could do to fix? The power cord and NMEA connectors have had no issues and stay connected. The sonar cable has been a PITA since I got the thing..
