Check data on Navionics card

[Hoghead]

I bought the Navionics upgrade card from CF to micro SD format and followed the instructions to register and download data to the micro SD card

All seemed to go well until I went to the boat and its new Ray eS127 MFD.
While the Ray recognizes that I have a S China Sea card plugged in, there is no detailed data on the card, and only a general overview.
Same problem on slot 2

I plugged the card into a neighbours boat and no data on my card.
His card in my MFD showed all the data

I brought the card home and just updated on the Navionics site.
How to check that the data is in fact on the card?
