Hi there are no updates as of yet but if its the firmware update you need to download music don't download any from the internet thats not from sony it will corrupt the files. Just upload music on itunes then with the MP3 player plug-in open two documents one for the NWZ-B153 and the other itunes then drag and drop the music you want to the MP3 player convert all music it takes long but at least you can use the MP3 player. Hope this message is helpful.
