Can i replace my 330c head unit with the 525c using the same wires antennae etc lowrance


Hope its not to late, before you replace (buy a new one) call Lowrance. I have a 525 and working through some problems and they advised me that they would replace my unit for $200 no questions asked. To answer your question not 100% positive but I did see a recent question where Lowrance lost his unit and sent him the 525 as a replacement and the connections were different. I believe my 525 has a 5 pin system with one notch. Does yours have a external gps module? The 525 does!

Cannot get a GPS signal to my 525c DF


This may or may not offer help but on the lowrance site it has very simple step by step instruction to solving this problem. The first step is to make sure your getting power to the new 4000 series. With a 12v tester you can do this. On the gps unit there is 3 different power sources. One is main power, two is sonar and three is power to data. One you have power going to the 4000 then proceed to other options. I hope you didnt pay full price for your 4000. Lowrance has a replacement process and replaced my 2000 for a 4000 for $120 (2 day shipping). Back to your situation... Out the back of the data will the a cord that connects into the bottom of the T, and the a resistor on one side and the 4000 on the other side.

Why cant I download my waypoint data to a 2 GB SD card. My Global map 5000c does not recognise the 2GB SD card. Do I need MMC/SD. Can I place the sd card in the slot beside the chart card ?. Thanks


You can place the SD card into the slot beside the chart card.

With the SD card in the GlobalMap unit by itself (take the chart card out), press MENU twice and choose BROWSE FILES. Does the unit indicate that an SD card is present? If yes, the card is working fine in that slot. Try the same thing in the other slot. If it only recognizes the SD card in one of the slots, the other slot is bad and probably won't work with any card. If the card is recognized in the BROWSE FILES menu, but the data that is on the card is not working, there could be compatibility issues with the data and the GlobalMap 5000.

Make sure the GlobalMap 5000 has the latest software update from http://www.lowrance.com/en/Products/Legacy-Products/GlobalMap-5000C/Downloads/GlobalMap-5000C-Software-Update-180/. You might need to get a different, smaller capacity card since your 2GB is not working.

If the 2GB SD card still isn't recognized in the BROWSE FILES menu after the update, the GlobalMap 5000 is not going to work with that 2GB card. You will want to get a different card. I suggest 1GB and smaller.

If this doesn't help, please let me know some more details. Is the 2GB SD card recognized in the BROWSE FILES menu. What are you seeing that makes you determine it does not recognize this card? What files are currently on this card? What kind of card is it (brand, model).

Hi,when i switch on my lms-332c the map does not come up on the screen.If I remove and replace the map card it works perfectly. Can I fix this? regards nigel


I am guessing that the card you are using is a NAVIONICS chart? There have been some Lowrance units that were made around the same time that have had problems recognizing a Navionics chart right from power up.

Make sure the LMS-332 has the latest firmware version which can be downloaded from http://www.lowrance.com/en/Products/Marine/Full-Size-SonarGPS-Chartplotter-Combos/LMS-332C/Downloads/LMS-332C-Software-Update/

If the update doesn't help, this is going to be a compatibility problem with the LMS-332 and that particular card. You will need to replace the card or upgrade to a newer unit...but probably can just get used to removing and replacing the card when you turn the unit on.

HAVING A PROBLEM WITH MY LOWRANCE 525C WITH EXTERNAL ANTENNA. IT KEEPS TELLING ME GPS MODULE NOT RESPONDING. I HAVE CHECKED ALL CONECTIONS AND CANNOT FIND A PROBLEM. WHAT NEXT


Make sure that you have powered the NMEA 2000 network. The display unit's power cable has a set of red, black, and sheild wires that need to be hooked up to a 12VDC power source. There is a power diagram somewhere in the manual that should show this.

Make sure that you have the NMEA 2000 network connected properly. If it is a newer version LMS-525, it should just be a single 15ft cable that has two female ends, the module plugs into one end, and the other end plugs into the back of the display.
If it came with some T connecters and 120Ohm Terminator caps, then make sure you have that hooked up correctly. There should be a diagram in the manual for that as well but you just connect the two T's together like TT, put the 120Ohm terminators at each end, and run the extensions to the display and GPS module.

There is a decent troubleshooting guide for checking to make sure power is getting to the module at http://primus.lowrance.com/support/resultDisplay.do?gotoLink=92&docType=1000&contextId=426%3A92.273%2C600.639%2C92.113&clusterName=ClusterPublic&lang=english&docset=%2FDocuments%2FTroubleShooting%2FNew+Utility&contentId=42296cce-4f9b-40c8-9dcf-33d5df754009&responseId=135ccbe2cfd4f608%3A1fe88d%3A1225c5cc17c%3A-bac&groupId=4&answerGroup=1&score=986&page=http%3A%2F%2Fprimus.lowrance.com%2Ficr%2FTroubleShooting%2FNew+Utility%2FNU_GPS_ModNR.htm&result=0&excerpt=Module+Not+Responding+The+GPS+module+not+responding+(early+GPS+products+may+also+indicate+coupler+not+responding)+indicates+that+the+unit+and+module+are+no+longer+communicating.&question=gps+module+not+responding&resultType=5000#Goto92

If this doesn't tell you anything, most likely the GPS module is bad.You will need to contact Lowrance support to get it repaired/replaced. You can call them at 800-324-1356 or email them at http://www.lowrance.com/en/Support/Product-Support/Contact/

MapCreate Topo does not have lake maps. There are 'some' maps on Lowrance's web site (Free Enhanced Lake Maps) but you may need to purchase lake maps on SD cards for the area you're interested in.

Data card lost all it data


I don't know how it would have "lost" all it's data. More likely is all of it's data was "erased" or "deleted".

Take the card out and put it into your computer or someone else's Iway and see if the file folder is still on there. It probably is. You might just need to reset your Iway. You also might try downloading the newest software update (ver 1.3) from the Lowrance website. http://www.lowrance.com/en/Products/Automotive/iWAY-250C/Downloads/iWAY-250C-Software-Update/
This is not the maps, it's just the software for the unit itself.

If the map file actually isn't on the card anymore, then ask yourself:
Did you make a data card backup to your computer like the user manual suggests?
If yes, put the backup file onto a 2GB SD card and stick it back into your Iway.
If no, then you're out about $90 to buy a new set of maps. They come from Navtec, you can't buy them from Lowrance because Lowrance doesn't produce them.
Good luck

My Lowrance LMS-337c df keeps going crazy.


Normal 0 false false false MicrosoftInternetExplorer4 st1:*{behavior:url(#ieooui) } /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}This could be caused by glitch in the operating systemsoftware or by low voltage due to a short in the unit or somewhere in the boatswiring. To troubleshoot the problem Iwould recommend the following steps.

  1. Try a soft reset
  2. If the problem resurfaces, try a hard reset
  3. Update the the operating system software

Soft Reset (Does not delete GPSData)
1. Turn unit OFF 2. Press and holdthe PAGES key
3. Press and hold the PWR key
4. Release both buttons when the USA map
Appears

Hard Reset (Deletes stored GPS Data
such as Waypoints and trails)
1. Back up any waypoints, routes,and trails that you want to save on a blank MMC card
2. Turn unit OFF
3. Press and hold the ZIN&ZOUTKeys at
the same time
4. Pressand hold the PWR key
5. Release both buttons when the USAmap
appears

To update the operating system software, check out this link:

If you don't have a card reader I can program an update card for you.
