The latest versions of iPod software and iTunes add Podcast features to iPod. iPod Updater 2005-6-26 and later adds a Podcast menu to any iPod with a Click Wheel. For iPods without a Click Wheel, iTunes 4.9 and later creates a Podcasts playlist on the iPod (it will do the same on Click Wheel models that haven't been updated with iPod Updater 2005-6-26 or later).
Depending on what software you install and how you install it, your iPod may experience one of the following issues:
If you install iPod Updater 2005-6-26 or later on an iPod without a Click Wheel, it won't add a Podcasts menu. Instead, install iTunes 4.9 or later, which will create a Podcasts playlist on the iPod.
If you install iTunes 4.9 or later, manually sync an iPod with a Click Wheel with it, and then update your iPod with iPod Updater 2005-6-26 or later, you will have a Podcasts playlist and a Podcasts menu. To remove the Podcasts playlist, temporarily set your iPod to sync Podcasts automatically in iTunes Preferences. To do this:
You can change it back to a manual sync if you prefer. Because the Podcast playlist was there from an earlier firmware version, it will not return.
