Once again Im sure there's an easy answer for this question, so here it is. I purchased my own sandisk ultra plus card 16 gb and after I installed it said no video card. So in thinking I must format any new card used. So how do I do that hook usb to phantom then computer then what dji assiatant app or what. I appreciate the basic explaination of what I should do Im sure others had this problem also. Again thankyou for helping, god bless and happy flying.
