32GB card will work fine.
I have a 64 gb card in the X9 and it works perfectly.
I never encountered a problem with that so far, and my 64 gb card is bursting at the seams, I have like 1.2 gb left.
Thanks for the info guys.
No problems with file limits?
Are there any special tricks to get the 64 gig card to work other than formatting it to fat32?
Nope, though my first 64 gig card was a Sandisk lemon... These things appear to be sort of a lottery; it is, or at least was, a recurrent problem. Had to return it and exchange it for another.
