If you received an Apple® Universal Dock Adapter with your iPod®, use it with the SoundDock® system insert for Apple® Universal Dock Adapter, as shown:
If you do not have an Apple® Universal Dock Adapter or the SoundDock® system insert for Apple® Universal Dock Adapter, the following chart will help you determine which SoundDock® system insert to use with your iPod® model. You'll find the label on the bottom of the insert.
Note: The classic SoundDock® system is not a "Works with iPhone"-certified product. It does, however, play music with the original iPhone® and iPhone® 3G (in the event of audio interference, set the iPhone® to Airplane Mode). You can use SoundDock® system insert A for your iPhone®. Or, if you prefer a more snug fit, Apple® offers an iPhone® Universal Dock Adapter 3-pack. Use these adapters with the SoundDock® system insert for Apple® Universal Dock Adapter. Also, the iPhone® 3G does not recharge when docked in the system. Use the iPhone® 3G charger, supplied by Apple® with your 3G iPhone®, to recharge your iPhone®.
Older SoundDock® systems were delivered with the insert models pictured below. They are compatible with the iPod® models indicated on their labels. These labels appear on the bottom of the inserts, as shown.
