Sean, Icon and Braille+ cannot use Micro-SD of any size. only regular mini-SD are compatible with Icon and BP, with maximum size of 2GB. These cards are now extremely difficult to find ... I recommend that you get a USB thumb drive instead. There are thumb drives as large as 64GB or more. Guido Guido D. Corona Levelstar LLC. 685 S.
