If you have an older version of the bootloader, the following directions will work:

First, shut down the device. Then, press MENU or SELECT to wake up your iPod.

How do I access music that I have transferred to my iPod using iTunes

iTunes stores your music in the iPod_Control/Music folder on your iPod. This folder has the "hidden" attribute set, so you need to enable the "View all files" option in Rockbox to show this folder in the file browser.

However, iTunes obfuscates the filenames of your music by giving them names such as DLER.m4a in folders with names like F03. The folders do not match albums - the tracks are placed randomly in the different directory. The album/artist/title information is stored in a database file called itunesdb on your iPod. Rockbox does not read the information from this file.
