I used the Panasonic 16GB card that came with my Typhoon 5004k in the camera and it worked fine. I decided to get a bigger card, so I bought a PNY 32GB card. When I booted up the unit I got a message saying the SD card was not recognized. I put the original card back in and it worked fine. Any idea what's going on? I know the card is supposed to be Class 10 but it says nothing on the package about what class the new card is. There is a 4 on the card, but the Panasonic card has a 1 on it.
