Raymarine forum

my Dragonfly charts are no longer working correctly. This is with/without my updated Navionics card inserted. Seems like the the installed charts on the device is corrupted or something. When I put it in DEMO mode the Charts look awesome, but when I take it out of demo mode I get block edges and or coastlines. Doesn't show depths in charts or channels, this is in any detail mode. I may need to get a replacement card? any help would be awesome.

Thank you in advance.

It appears that there is either an issue with the microSD memory card, the data stored on it, or with the MFD's memory card reader. Please click here to view a FAQ addressing this subject. Using the information specified within the referenced FAQ, have you verified that your display's memory card reader is operational? If so, have you configured the display to select Navionics Nautical Charts within the Chart application being viewed?
