Question about Lowrance GPS

1 Answer

I have a 520c gps and fish finder, got it last summer, only been used about 7 times between last year and this year. Now all of a sudden the gps, doesn't show any satilites except one, and it won't lock on to it or time any other, satilites. So in other words, it doesn't work. I called Lorance and got voice mail and not answer back. I tried resetting the machine, disconneting and conneting the antenna, with no change. Is there a real problem or am I not finding the problem.

The problem is most likely in the antenna.

Have you installed a RADAR? The GPS will not acquie a saellite unless it is above or below the bea emitted from the RADAR.

The easiest thing to check is corrosion on the plug where it attaches to GPS.

Look at tour satellite status page. Is WAAS turned on or off? If it is on try turning it off and see if that makes a difference. If the GPS acquires with WAAS turned off, you probably need a software update.

Next follow the antenna wire to the antenna and look for any signs of damage, particularly where any new accessories have been installed. It is also a common point of failure if the cable is stressed near where it enters the antenna.

You may be able to convince your friendly local marine retailer such as West, Cabala, or Boater's World to let you buy an antenna for test purposes and then return it when you are done. You don't have to snake wires all over the boat, simply place the antenna somewhere where it has a clear view of the sky and plug it in.

If the antenna is not the culprit your next step would be to check your software version which appears when you start up the display. If it is not version 2.3.0, get a blank MMC card and download a software update from Lowrance at this link:
SOFTWARE VERSION 2.3.0

It should include intructions on how to install the update.

If that fails, your only option left is to box up the display and antenna and send it out for service.

Transducer loses bottom at any type of speed greater than trolling. Worked fine last year with all the same setttings. All I can think of is , maybe the battery is low. The boat just came out of storage...


Check the transducer for any damage on the front part. Also make sure there isn't any damage on the bottom of the boat that is causing air bubbles to cross the face of the transducer. If it works at slow speeds there is definitely something causing air bubbles.

Problem with navman 4150 fish finder


I installed my Navman 4150 depth finder along with the Navman GPS unit when I purchased my Bayliner Trophy 20Ft. Offshore model. Everything was ok for one year and it has been downhill since then. Losing signal, unbelievable high depth ranges, blank periods, etc.. I now can't even get a reading tieded up at the dock. I am now giving up and shoping for a quality unit.. Cape Disappointment.........

4150sx finder erratic depth


I had the same problem last time I was out in shallow water (in less than 2 metres of water) and I suspect that the problem was weed wrapped around the transducer but won't know for sure until I take it out on the water again. I had another problem re water temp which I'll enter separately.

I Experienced the same problem the last two weeks. I read your suggestion about the right key/power button. The GPS asked me wheter I wanted to clear the memory yes or no. After "yes" i had to reenter my country and date/time. After doing this it took gps310 more than an hour to get its first fix. But it works again.
