Hi Lindoz,

I have been able to use the same SD card in both my Kn7000 and digital camera (a Polaroid PDC3350). The important thing is to format it in only one device. It can then be inserted in the other which should then create the necessary folder(s) for storage of its unique information. It doesn't matter which device is used for the intial format.
I have also used the camera in conjunction with my laptop as a card reader for KN7000 SD cards with the backup and restore functions of Technics Song Manager software.

Cheers
Len C.
