How do I use my SD card slot?
You can copy individual music clips onto an SD card using an SD card
reader/writer attached to your PC. Insert the SD card into the Aireo player.
Aireo reads the SD card and makes it available for browsing on the MP3
Player view. The songs on the SD card appear as an Unknown
playlist along with any music clips that were simply dragged-and-dropped
from Window via Aireo’s drive letter. Note that Aireo does not read playlists
from the SD card.
