I've just bought a Bug DAB radio which also plays MP3 files from an SD card.
I must admit I'm a bit dissapointed with the MP3 firmware. You have to put all the MP3 files in a TRACKS directory on the SD card. All files have to be a maximum of 8 characters long and not include certain charaters.
There seems to be no way of browsing by artist or album name, everything goes in a long list and you scroll up and down the list.
I have bouught a 1 Gig card so have room for about 300 tracks, I normally use itunes to organise my music.
Has anybody got a good way of selecting the mp3 files that I want on the SD card and renaming them easily to the right format?
