The only reason I am answering this is you have had over 300 views and no an answers. I have been doing a lot of research on the BJ II and in one of the reviews a gentleman put an 8 gig in just to see if it would work. It read it and showed he had used over 2 gigs of music so chances are good it will work. I am a rookie at this so don't take it for gospel, just what I saw.
