Hi Lindoz,
mine didn't work together. Once using a (empty/new) card in eighter the kn7 or the camera you have to format that card to use in one of the two. During the format all the data on the card will be overwriten. The camera or the kn7 makes after the formatting their own OS-structure on the card.
I can use the card only with e.g. explorer to put data on the card in a SEPARATE folder. That's no problem. Be aware not to delete or overwrite any data use by the camera/keyboard OS.
Greetings,
Cees
