How to Set-Up an iPod Nano: Fifth Step

The Photos and Contacts tabs are the only two sections that don't reference media contained within iTunes. Depending on whether you're on a Mac or PC, the Contacts tab (a rarely used feature) will allow you to pull data from whatever preferred contact and calendar programs you have on your computer.

For photos (shown here), users have the option to sync entire folders of images stored on your computer, or select specific sub-folders within larger collections. Users also have the option of importing videos from these folders or transferring high-resolution versions of the photos for playback on a connected television (accessory required).

This is another optional step, we can instead use our mobile phone to manage your contact. But this was just another great feature from iPod Nano 5G.
