Multiple Navionics+ Cards in eS series MFD

[lkgreen]

Navionics advised me they were aware of the issue and provided a workaround which requires changing the name of a particular file with the file extension of .ck
I made the suggested changes and I can now read the detailed charts when one card is inserted in each slot. When I insert a card in the 2nd MFD it does not show the detailed chart boundaries for the third card in the system. Both chart plotters seem to be working as expected with the two cards loaded in the one plotter.
Navionics Tech Support indicated they were working on a solution to the issue which did not involve the workaround of changing a couple of file names. They were under the impression that Raymarine was also working on the issue.
Thanks for your assistance in this and I will stay abreast of any notifications that a permanent solution has been found.
