Lowrance 520 _LGC 3000 gps puck. Keep losing GPS signal

**HairyVetch** · 03-30-2011, 12:06 PM

Hi Guys,

For better or worse I mounted my GPS puck in front of the console in front of the windshield. it has been like this for > 2 years without much issue but lately i cannot keep a signal and GPS is almost useless. Nothing is different then it has been. Would the issue most likely be with the head unit or the puck? Is there anything I can do to troubleshoot this?

Knowing what I know now I would have mounted this on back by transducer and I may still do that later.

make sure waas isn't check mark and try unplug and replug the connections make sure there getting a good solid connection.

I have a Lowrance 480 lms that does the same thing ! I was told it was the puck (LGC 2000)

I will look at the setting and double check my connections when I get home. I will let you know if that resolves it. I sure hope it does.

Can you buy a new puck ( LGC 2000) ? Went to Lowrance web site & didn't see any.

This replaces the 3000. I got it because of the refresh rate. Works on most lcx and HDS. It is Nema 2000, not Nmea 0183

Don't ask me how this picture got on this post. It didn't show in the reply and I can't edit it out.

Reckon it will replace the 2000 ?

It will work with lcx and HDS. That is all I know. I have lcx and HDS NMEA2000 networked and both work fine. I don't get the fast refresh ( 5 times per second) with the lcx though.

I haven't used it much, but the lcg4000 really improves HDS gps performance. Mainly, I don't loose signal on the west bank of the lake near banks.

lms has blue nmea connector? if so, the lcg4000 should work but you have to buy the blue to red converter cable. just a thought.
