Question about Furuno NavNet 3D Hub

1 Answer

Purchased a used boat and have a nav net unit on board. I am able to get most things to work but get a stand by on the screen on the sounder mode and unable to get it to function. Any ideas why. I assume it is my lack of knowledge.

I have a furuno fcv 582l. The unit has just come back from the factory and works well until I power up any other electronic equipment on the boat. Then it flickers and the screen goes dark. Any ideas?


You likely have inadequate supply to your helm. Otherwise, there is interference being generated. Try turning things on slowly one at a time, check your batteries and ground connections.

I can never read the fish on the screen of my sounder whether is in auto or manual mode (yes we are catching fish)


perhaps someone has messed with your sounder settings. You may want to factory reset the sounder from within one of the menus in your navnet. Also you may have a transducer going bad. Did you hit anything with it or run aground once? Maybe someone painted over the face of the transducer with bottom paint. There's alot of things that can cause this to happen. It would be best to have the sounder checked out before you do anything to the ducer. Remove your navnet and sounder and take it to a dealer to test on the bench. If you're in the maryland area, Mid-shore Electronics and handle this for you. Even if you're not, you can send the units to them.

Locks up after a few seconds/have to kill power to reset


This may help. Mine has the GPS antenna build into the bracket at the back. I removed the bracket and the unit did not go into the error screen and the sounder worked fine. The GPS would not locate but it has not antenna attached so DOH!! I have orderd a new antenna with the BNC connector and will post if that fixes the problem. At this point I'm guessing its a blow GPS antenna.

Sounder not working


Interference like that is usually caused by electrical noise. Does it happen when everything else on the boat is turned off? If the answer is no, then you can isolate the source of the interference by turning things on one at time. Follow your transducer cable and make sure it has not been damaged or altered in any way.

Also make sure that your gain is set to auto

The GSD 21 has an LED indicator light on it. If it detects a malfunction the LED will flash in distinct colors or patterns. In the troubleshooting section of the owners manual there is a list that explains what each flash pattern means.

WAAS


sounds like the problem is with the pilot. You may be expecting too much from nav mode you should check the antenna connector on the WAAS issue
on VX2, are you marking a good bottom on the sonar screen, but have no digital overlaid? never seen it, must be a BB thing

I have been doing some research and I haven’t been able to determine if the Garmin has a compatible output for your Furuno. I can not recommend any service center particularly since I have no idea where you are located, but any good marine shop should be able to help you.

The Furuno uses NMEA Inputs for the GPS, and like I said I haven’t been able to determine if that Garmin uses that as an output. I would suggest that you inspect your installation to determine if there are any cableing between the two units. If no wires connect the two that you can be sure that the units are not communicating.

As far as the chartplotter goes you can buy data cards for them, either on-line or from a good marine supply store.
