I saw somebody posted a message saying you could use an SD card up to 32Gb. However, in the 900BT manual it says:
SD
Compatible physical format - Version 2.00
Max capacity memory - 8Gb
File System - FAT16, FAT32
Decoding format - MP3/WMA/AAC/WAVE/MPEG4
It also says it DOES NOT support SDHC, which is a big downer. I thought non SDHC cards only came in sizes of 2gb maximum.
right, non-SDHC cards only come in sizes of 2gb max. but since that quote you posted mentioned "Max capacity memory - 8Gb", that means SDHC is supported.
