Lighthouse Chart on Navionics card

[Chuck - Raymarine - Moderator]

Al,

Unfortunately, there's nothing that I can immediately point to, as the LightHouse chart files stored on the chart card would be those which would be expected. Technically, there's no reason that LightHouse charts may not be downloaded to a Navionics chart card. However, as indicated within my initial response, the LightHouse II v19.03 software will not permit a LightHouse_id.txt file to be saved to a microSD memory card containing Navionics cartography. The most common cause for reports of being unable to view LightHouse charts involve a LightHouse_id.txt file and/or LightHouse chart files which had been copied from another microSD memory card, thereby causing a conflict with the LightHouse chart encryption. At this point, it is recommended that the following files be deleted from the root level directory of the chart card:
- *.rx5
- *.r01
- *.r02
- *.txt
- *.pdf
- LightHouse_id.txt

After doing so, another microSD memory card should then be used for your LightHouse charts.
