The A1051 model of the iPod was more commonly known as the iPod Mini. Released in 2004, its biggest distinction was that it introduced the Click Wheel you see on all current iPod classics and older iPod nanos. Apple discontinued the A1051 model in 2005 along with the iPod Mini line. You can find used models with 4- and 6-GB hard drives. You operate the unit much like other iPod models that use a Click Wheel.
Press the button or any surface on the Click Wheel to wake the iPod. A list of options appears.
Move your finger clockwise along the edge of the Click Wheel to move the cursor down the options list. To move the cursor back up the list, move your finger counter-clockwise on the Click Wheel.
Press the centre button when you reach the "Music" option.
Select how you want to list your music: by artist, playlist, genre or album.
