"GPS Module not Responding"

[Simon B]

Our Lowrance 3500C keeps outputting this error message, we have checked the NMEA bus and it seems ok. We also checked how long it took for the unit to see that we'd disconnected it this was around 4-5 seconds. Therefore, we don't think it's losing power.

Has anyone else regularly had this problem? It will go away most of the time when you down power then re power.

Hi,

We too have had this problem. Do you have the Lowrance 'blue' tee pieces?

I gather there are some issues and they have now redesigned the connectors. They are not backwards compatible!

Our GPS module started to drop off line. Eventually we had to replace the tee piece. Is yours mounted anywhere damp?? There was also an issue with the connectors not locking and lacking a firm detent to confirm locking.

Give me a PM if you want the whole saga, or a number to call me.

I would add that Lowrance have been very helpful. Could be that the Boat Show is a good place to raise the issue with the manufacturer.

Our Lowrance chartplotter started outputing the same error message this Saturday. I powered off then on but it continues to display the message.

Have asked rib shop to have a look and report back.

i have the same problem but intermittent. I did have the ariel replaced which solved the problem for a while, now when it happens i just turn the thing on and off a few times. Another problem i have is that if i do not turn off the power at the isolator switch the plotter seems to switch on itself - well it flickers and omitts a beeping sound, again switching it on and off solves the problem

Interesting, we have another possibly related fault, we can power down the sonar - Lowrance 107CDF and the transducer will keeping pinging away like its still swithced on, which it probably is. As stated in other posts a repower/downpower stops it.

I've not seen ours switch on by itself yet but will look out for this. Other than this I cant fault the 2 instruments. The NauticPath chart card seems excellent for what we use it for.

Hello,

Try a soft, at first, and if it's still wrong, a hard reset.

Good luck.

This is probably a connection issue but what software version are you running in the LGC2000?

I had the same problem after putting the Lowrance fuel flow sensor in the network. Connected everything according to the Lowrance specs.
However, after upgrading the software version of the LCG2000 the problem went away.
