Sixth-generation Apple iPod nano is no longer supported by Apple
With its square design and small size, the sixth-generation iPod nano could be converted to an early "dumbed-down" version of the Apple Watch with the help of third party straps. This particular model removed the click wheel, video camera and a speaker from the fifth-generation variant. Instead, the newer unit carried a touchscreen, and the iPod Shuffle's clip helped attach it to the user's clothing.
In California, the state requires that Apple continue to provide service to the device through September 2019. If you live in the state and your sixth-gen iPod nano needs service, visit the Apple Store closest to you, or call AppleCare at 1-800-APL-CARE.
