I bought a 1gig micro SD card at best buy and I loaded it up with mp3 files. used the ez- b and the mp3 trigger to play a files and I get a 3 sec delay in sound. Now I'm thinking it due to the SD card, I know the card must support FAT16 format but I can't tell it the card is FAT 16 , it just says micro SD card. Any in sight? Is the card SDSC?
