I can get my unit to actually see my 4Gig Micro SD card. But it won;t see any cards bigger than that. It is supposed to use cards up to 32 GiGs. But apparently all cards above 4Gig are Micro SD HC cards and I can not get it to see any of these Micro SD HC cards. I have placed the card in the slot and rebooted the unit as suggested by the tech support, Still no recognition of card. What sort of format does it recoignbise. I have tried Fat , FAT 32 , exFAT , but it does not seem to make any difference. Is there another type I should try . I have not tried NTFS yet. Any comments would be great from a newbie at this tablet thing.
