    Unit keeps powering back on by itself. when it is "on" it blinks constantly. i try to turn it off and it powers back up. it keeps draining my battery when the boat is parked.

    I have the same problem with my LMS-337CDF. I got it with a second hand boat I purchased in November. It has always powered itself up with the display flashing and audio alarm going off. Is the operating system upgrade worth trying? I don't have a card reader to experiment with.

    I tried the soft and hard reset, no joy.  Got a card reader and down loaded software.  System worked until I installed the SD card with maps on it.  Reloaded software and got it to work with Map card installed.  I was doing all this on my work bench with the battery from the boat.  Now that I have the system installed on the boat the problem returned.  I'm going to double check the wire connections and run the negative and shield wires separately as home runs back to the battery.  After that I'm going shopping for a Garmin.

Mine does the same thing when the voltage is low. The GPS part will drain the battery if left connected. Learned the hard way. I installed a battery isolator switch, the one with the big red key, and switch the battery to "Off" when finished. Either that or unplug your unit each time. Still, if the battery is not maintained during storage, the same problem will arise until the battery has been fully charged. Never has done this when the outboard is running and current is going to the battery from the alternator.

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.

the lcd is going out and will cost more to fix it then the cost of the gps....my advice is to get a new one from bestbuy and get the 4 yr performance service replacement plan so next time you have a problem like this they will replace it for free.

Is there an external antennae for the lms 527 combo available


  • No it does not. Lawrance often makes either external or internal GPS units. This is an internal antenna unit only model. Hope this helps.

I turn my power source on and my screen flashes like it's not reading anything from my transducer but the transducer is new.


Has this unit worked in the past, or are the transducer and the unit itself new? Is this a Lowrance LMS-240 as indicated before your question?

Please let me know and I can help you out here.

Thanks, just reply here,
Tim

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.

Gps


I have a manual for this unit but i'm still using mine so not willing to sell it to you. I'm in Melbourne and you're welcome to borrow it for a week or so or i could probably photocopy/scan certain sections for you and email them if it helps. Let me know if you still need it by emailing me at joshklat@hotmail.com

Cheers,
Josh
