Troubleshooting my Lowrance LC X - 15MT Unit

Hi,

Please test the backup sd card on another GPS if possible to see if the zoomed-in section of the map file shows up or not. If it shows, then you'd need to send in your lowrance gps for repair from the water damage.

Thank you.

With your card in your unit follow these steps it should accomplish letting you view your map data.
push MENU twice
Highlight CHART push ENTER
Highlight CHART DATA push ENTER
Highlight LOWRANCE push ENTER.
You will note there is an option for Lowrance and Navionics, if you select Navionics you will see a distinct difference in the way the base map displays on your unit.
Hope this helps.

Yes, all Lowrance products will use and display Navionics map data.

Hello :

I recommend you to reset your device to fix the problem .

Here is how to reset your GPS :

1. Turn unit OFF
2. Press and hold the PAGES key
3. Press and hold the PWR key
4. Release both buttons when the USA map appears
..........................................................................................

Here is how to hard reset your GPS . But be careful because Hard Reset (Deletes stored GPS Data such as Waypoints and trails)

1. Turn unit OFF
2. Press and hold the ZIN&ZOUT Keys at the same time
3. Press and hold the PWR key
4. Release both buttons when the USA map appears

PLEASE DON'T FORGET TO RATE !

Marine maps must be installed on SD cards. The base-map does not contain marine maps. Most on-line or brick-and-mortar hunting/fishing stores carry map cards for Lowrance units.

I had the same problem with my handheld Lowrance Hunt C. After installing the card and locking it in place, I had to slide the card "out" toward the locking mechanism. It barely moves, but worked after that. Whenever I load the card, I now slide it out and it works every time.

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

Have you highlighted the section with the map select tool, then hit the Transfer to GPS button? If you do, what happens then? Does it freeze?

If you are able to send routes and waypoints to the unit, you should be able to send selected unlocked maps as well.

Try a soft reset first, if that doesn't correct it try a hard reset. BE SURE and Save Data before th eHard Reset, it clears all waypoints and such.
