Happy Holidays,
Our BeoSound 3 has been in our living room for years, and this holiday season we put it in our daughter's room so she could have some higher-quality music.
i tested the device and it was working perfectly. it took the sd card out to change the music. after some fooling around, i have re-formatted the card and it is not read by the BeoSound 3.
I formatted the SD card in FAT (from a PC) with default allocation size. I even went back to the initial music files that worked before the re-format and no luck.
