For one thing, it's larger and has a bigger screen to go along with its size. For another, it now has a Home button, something that had previously only shown up on iOS devices like the iPhone and iPad. So, just by looking at it, you know that there are major hardware changes here. Apple discontinued the iPod nano line on July 27, 2017. The diagram and these explanations explain what each button and port on the 7th Generation iPod nano does. Hold Button: This button at the top-right edge of the nano is used to lock and unlock the nano's screen. Holding it down turns the nano off or on. It's also used to restart a frozen nano.Home Button: This button takes you back to the home screen (the screen that shows the basic set of apps that come pre-installed on the nano) from any app. It's also used in restarting the nano. This is the first model that had an iPhone-style home button.Lightning dock connector: This small, thin port replaces the Dock Connector used on all previous nano models. Plug in the included Lightning cable here to sync the nano with a computer, or connect accessories like speaker docks or car stereo adapters.Headphone Jack: This jack on the bottom left of the nano is where you plug in headphones to listen to music or videos. The 7th generation iPod nano does not have a built-in speaker, so plugging into the headphone jack is the only way to hear audio.Volume Buttons: There are two buttons on the side of the nano, spread a little bit apart from each other (there is a third button between them. More on that in a moment). Use them to control the volume of the audio playing through the headphones. The top button raises the volume, while the bottom button lowers it.Play/Pause Button: This button sits between the volume up and volume down buttons and is used to control music playback on the nano. If no music is playing, clicking this button starts it. If music is already playing, clicking it pauses the music. 7th Gen. iPod Nano Internal Hardware Features There is also a pair of interesting hardware features that are internal to the nano and so can't be seen: Bluetooth: The 7th Generation iPod nano is the first nano model to offer Bluetooth. Bluetooth is a wireless networking option that lets you stream music to Bluetooth-enabled headphones, speakers, and car stereo adapters. You won't see the Bluetooth chip, but you can turn it on via software when compatible devices that you want to use are nearby.Nike+: The Nike+ system lets users track their workouts using an app, a device, and a receiver that's often inserted into a compatible shoe. With this version of the nano, you can forget the shoe insert because the Nike+ hardware and software are built-in. Thanks to the nano's pedometer feature and Nike+, you can keep track of your exercise. Add in Bluetooth and you can connect to heart rate monitors, too.
