Question about Lowrance LC X-15MT Sonar

Troubleshooting my Lowrance LC X - 15MT Unit

I can't display any Navonics maps on my unit. When I go into Map Data, the section under Navonics Maps says "none" even when I load both chips. I can't find a "Use Navonics Maps" box to be checked on my unit. I know the maps are there as the files are shown when I go into the "Browse MMIC" command. I also know the chips are good as I have loaded them into another unit. What's happening?? Thanks for your help!

Lowrance mark 5x will not come on

Posted on Aug 22, 2011


All of my lowrance products ar very particular to cards. Both my I-finder and my X-15MT would not read cards that other readers would read. I finally have three cards that work and guard them very carefully. PS. I found this via Lowrance troubleshooting and received great help from a tech there. You can check the cards before registering them by placing them in your unit and see if it shows the card present.

I cannot bring up a marine chart showing depth and markers on my

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.

Global map 5200c loading problems- navionics platinum hot maps

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.

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.
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.
