Lowrance 520C

11 posts in this topic

I have a 520C and I lose the bottom on the sonar constantly. From what I have researched I need to update the software. I did so but my unit didn't take the upgrade.

Does anyone have any experience loading the software. I loaded it on a MMC card and put it in the unit and turned it on and nothing happens. I do to the software version and it still says 1.4 not the 2.3

Any suggestions?

Thanks,

Paul

You may have special instructions on the lowrance site for downloading on your particular devices. Extraction instructions and stuff. The update for the 525 was a dream.

Did you download the update file which has a *.exe extension?

After downloading that file, double-click it and let the self-extractor lead you through the process. It'll ask where you want the files stored (which will be the MMC card) and if you want the update files to be automatically deleted from the MMC card upon completion of the update which is totally up to you. After it has loaded the file onto the card all you should have to do is insert it into the 520c and power it up. Be sure that you are using a completely blank MMC card when loading the update files. It seems to help.

You will also want to make sure that your MMC card is no larger then 1 GB or your unit might not recognize it. Just had that problem with my H2O and had to go back and read some old threads and was able to do the upgrade with no problem.

Check your sensitivity setting on it as well. I have the 522c and on the recomendation of another post I set it down to like 50% and it read the bottom in shallow water fine then.

You are not alone. Check the older threads and you should be able to mix some suggestions into a solution. I had the same problem with my 522 and I recently installed the update and now it works a lot better. As Sandmannd suggested, I've been trying to adjust sensitivity manually and it seems to be helping out quite a bit. Good luck!

I have the exact unit and have been having the same problems I loaded the software one time and it work perfect on Mille lac and then few days on a metro lake later it didn't work worth a c r a p. So I loaded it again and the last time out it work alright. What ever happen to when you could by a high buck item and it would last for many years and you didn't have to load a bunch of c r a p on it? It worked fine when I installed it last year .What changes of the winter that you need to do all this?

Thanks for the help! I updated my unit and it flashed originally but once we started to move after I adjusted the sensitivity it worked good. We were on a very shallow weedy lake also.

    • Three favorites at the moment.  By the time they upload, I may change my mind.
    • A few from Maplewood State Park on April 16th.  Non-professional, but they stood still long enough for me to get 'em.
    • You might be able to figure things out this week.  How big is your sump basket?  Is the  pump kicking in now?  Sit there for 15 minutes and count the number of times it cycles.  That should give you a decent idea on how much water is coming in.  Then figure out about how high the water has to go before it flows by gravity.  The spec for the pump will say something like that it can pump 2,000 gph at 10 feet of lift.  (the gph drops dramatically the higher it has to pump the water).  The answer to your specifics will give you an idea of how big of a pump you need.  If you match the size of the pump as close as possible to the amount of water your will face you can maximize the amount of time the battery backup will last.   Faced with this problem I took a standard boat sump pump and modified it so I could hook up a garden hose.  The I took an old shop extension cord and wired the pump so I could hook it up to a car in the garage.  So just prior to having Noah float by I could hook things up in the garage and be good to go for as long as I had gas in the car to pump up the battery.   Now that I am adult I bought a generator and wired the house to take care of things.
    • Inevitably at least twice each season I will leave the house, drive 45 minutes and walk some of my favorite grouse spots for hours and hours, seeing nothing.  Admitting defeat on that day, I will drive 45 minutes back home, only to find a covey of birds in the driveway...

    • Hey featherslayer, you gonna register that nice bird of yours pretty soon?
    • cool find!  sure looks like a Swainson's.  
    • Great info.   Thanks Steve!   Jim
    • Came across this hawk on Earth Day at the edge of town. I've been told dark morph Red-tail, dark morph Swainson's and dark morph Broa- winged. Anyway, it's a dark morph some kind of hawk.
