I just put in a new 64 GB micro SD card and went out flying. At start up, before even take off I noticed I had no image on my screen (ipad mini 2). Pushing the video camera & photo button worked but no image on ipad, I could here the sound for video on & off and when each still image was taken. I turned off my P4 and ipad and tried again, no luck. I formatted the SD card, no luck. I put in the factory 16 GB card, no luck so I returned home, only minutes away. After lunch I tried again in my own backyard and it worked fine. Any idea why this happened? I don't want problems when I am out in the field and ready to capture some real scenery.
