    • What's lean, new, and green? The iPod Nano 7th Generation. The Nano is available in several colors, but we decided green was the way to go.

    • Completely redesigned, the 7th Generation Nano takes after its iPod Touch and iPhone brethren.

    • Tech Specs:

    • 16 GB storage capacity

    • 2.5-inch (diagonal) widescreen Multi-Touch display

    • Built-in accelerometer

    • Bluetooth 4.0

    • We're beginning to think that Apple doesn't trust us with unboxing their precious gadgets — so we tried it their way.

    • Their unboxing procedure was neither comfortable nor ergonomic.

    • We are happy, however, that there is minimal packaging between us and our new green friend.

    • Amidst the greenery we find the Nano's new model number: A1446.

    • With the slow phasing out of the iPod Shuffle and iPod Classic, it seems that Apple is gravitating towards a line of products based solely on how large of a device you want around your home button.

    • If you look closely, you'll see that the icon on the Nano's home button is round, rather than square, to match its circular icons.

    • Cowabunga, dude! What do you do with twice the screen size of the old Nano? You load minimalist illustrations of Ninja Turtles, duh.

    • Just how much bigger is it than the previous Nano? Oodles.

    • The 6th Generation Nano came in at 1.48 x 1.68 x 0.35 inches, and weighed 0.74 ounces.

    • The new 7th Generation is just over twice as tall, while also a little thinner and more narrow at 3.01 x 1.56 x 0.21 inches.

    • At 1.1 ounces, the newest Nano only gained an extra third of an ounce.

    • Reverting to the tall design utilized in previous generations makes the iPod easier to grip, and thereby easier to use. The designers threw the 6th Generation's clip out the window, so the new Nano is that much thinner.

    • Switching to the Lightning connector might have saved a little space in the iPhone 5, but its impact on the iPod Nano is pretty profound.

    • Guided by the sword plastic opening tool of our father, we were led to the knot tab that opened the pit of despair.

    • Hiding beneath the tab we find the Bluetooth antenna, which sneakily covers two Phillips screws that unlock the magic lurking within the Nano.

    This white part is NOT this easy to take off whatsoever and the bluetooth antenna often sticks to the white piece, causing the ribbon to tear. Just be careful.

    On mine its not plastic its metal which doenst open at all

    Guido Cautreels -

    Hi Can someone help me where can I get this little white part because mine is damaged

    • With the screws removed, we grab a plastic opening tool—our favorite way to crack open a new iPod.

    • After a bit of wiggling, we manage to pry the display assembly up from the rear case, only to be met with several cables blocking its complete removal.

    Tough luck if the front lens comes off before the rest of the assembly & it tears one of the ribbon cables

    David Maynard -

    There is a bunch of glue all around the edge of the screen lens. In addition, the screen and aluminum frame that holds it tends to stick to the lens and gets stuck easily on the outer frame. Taking this apart leaves very little room to work with, since the ribbon cables connecting the battery (glued to the back of the screen), screen and touchscreen lens are all very short.

    • Two quick flicks disconnect the LCD and digitizer cables, leaving only the battery cable as a final umbilical cord between the two halves of the device.

    • The battery is both adhered to the back of the display assembly and soldered to the logic board.

    • Unfortunately, the connivance and cost savings of adhesive come at the cost of repairability.

    • Pop goes the digitizer!

    • With just light adhesive around the edge, it's nice to have a part that finally comes off easily.

    • We've got a full house in our hand with the bezel, logic board and battery assembly, and the rear case.

    • We hope that the minds at Apple aren't as twisted as their cables. Cables with this much form probably come out of engineering efforts to make this iPod as thin as possible.

    • There's an adorable plastic pull tab underneath the battery. It's likely there for battery removal, but we aren't sure it's up to the task.

    • It seems the adhesive holding down the battery is much too strong for the feeble pull tab to break through.

    • Forgoing the tab in favor of some spudgering, we're able to pry the 3.7 V, 0.8 Wh, 220 mAh battery off the back of the display assembly.

    • 0.8 Wh is more than twice that of the iPod Nano 6th Generation's 0.39 Wh rating.

    "0.8 Wh is more than twice that of the iPod Nano 6th Generation's 0.39 Wh rating."

    Mostly because it has twice the screen ;)

    • By now, we are getting pretty anxious to pull out the logic board and get a look at what makes this Nano tick.

    • Alas, with all of the peripherals both soldered to the board and adhered/screwed to the case, we're still a couple steps away.

    • We're able to unscrew the bracket securing the volume buttons to the rear case and pull out the button cable.

    • Putting Bluetooth 4.0 in the iPod Nano means putting a Bluetooth 4.0 antenna in the iPod Nano.

    • We found this Nano's Bluetooth antenna easy to remove with a plastic opening tool—provided you've already got the case open.

    • Bluetooth connectivity in the Nano allows you to access your music wirelessly with Bluetooth-enabled speakers, headphones, and car stereos.

    • After enough poking and prying to earn ourselves certification as plastic surgeons, we finally gently yank out the logic board!

    • As in the iPod Touch 5th Generation, many of the important components—including the battery, Lightning connector, and volume controls—are soldered to the logic board.

    • With the logic board gone, the rear case is left all alone with no friends to keep it company. It's not easy being green, you know.

    • Pulling out the logic board really feels like pulling out the entire iPod—the battery, button cable, Lightning connector, and headphone jack all come with it.

    • On the flip-side we found an intriguing fibrous tape covering the EMI shields on the ICs. It's probably there to insulate against contact with the rear case.

  14. Drqx3BTMbRcgQyQC

    • A rundown of the ICs on the logic board:

    • Apple 338S1099

    • Broadcom BCM2078KUBG Bluetooth + FM radio

    • NXP Semiconductors 1609A1

    • 75203 23017

    • 75292 98820

  15. ILtUdl3VfdOlOc1p

    • Even more ICs:

    • Toshiba THGBX2G7D2JLA01 128 Gb (16 GB) NAND flash

    • Texas Instruments 343S0538 touchscreen controller

    • Apple 338S1146

    • 339S0193

    • iPod Nano 7th Generation Repairability: 5 out of 10 (10 is easiest to repair).

    • An easy-to-open case only requires unscrewing two screws and a plastic opening tool.

    • Only standard Phillips #00 screws are used—no security or pentalobe.

    • The LCD and digitizer glass are not fused together, allowing replacement of either component separately.

    • "External" screws hidden behind the antenna mean less adhesive holding down the display assembly.

    • The battery, Lightning connector, button cable, and headphone jack are all soldered to the logic board.

    • The battery is adhered to the back of the display assembly.

As usual, iFixit has decided that any integration, thinness, beauty or functionality is low on the list of importance. The most important thing is Lego like snap together and bulk.

Robert Evans -

I'd recommend you to read the iFixIt mission statement, but you'd figure out they're right soon enough when your first iProduct breaks one way or the other 1 month after the warranty expires..

Using screws and clips does not imply that a product cannot be slim and beautiful, btw.

denmike -

Have you been able to identify which DAC is used? Did Apple go back to a Wolfson chip?

Adrien -

Tried to replace a broken digitizer and ended up breaking the LCD. These instructions don't make clear in Step #6 how deep you need to get the opening tool in order to pull out the ENTIRE DISPLAY ASSEMBLY. The picture indicates, quite wrongly, that you only need to get the tip of the opening tool under the glass. This will result in separating the digitizer from the screen prematurely, and then breaking the LCD screen. The reality is that you must get the tool deep under the metal base of the assembly and pry the whole thing out with much force (it's glued on both sides). Frustrating.

Carl -

True, I broke the LCD screen with this method. Glue is everywhere in this device.

Axel -

Sir, this isnt a repair guide.

Tristan Haugh -

This is one of the worst guides I've found on here. How about you concentrate on actually getting vital information across, instead of making a thousand and one culture references? Vital information like "The bluetooth antenna is GLUED to the plastic cover, and you need to be very careful not to tear it." and "The LCD assembly is GLUED into the chassis, so you need to go deep with the case tool and use a fair bit of force. Breaking the screen is very easy to do."

Jeez.

Marcus -

Hi Marcus.

As indicated at the top of the page, teardowns are previews of the inside of a device and are not intended as disassembly instructions.

We have a full set of repair guides that are created especially to help you disassemble and reassemble your iPod safely.

Happy repairing!

James Pearson Hughes -

Agreed! There’s glue all over this thing and it def will not come apart the way this is written.

Era -

Say I wanted to remove the Bluetooth antenna; would it have any effect on the Nano other than the inability to connect via Bluetooth?

Erin Brennan -

I doubt it. Bluetooth simply won’t work.

Liam Powell -

Can you get a new headphone jack without buying the whole logicboard assembly?

jsunem -

Would like to learn same. It no longer accepts head phone jack.

Stanley Norris -

Hi there...I was looking on the web to find the buton volume on the side...not the flat cable but only the volume key made in alluminium...do you know any place where can I find it and buy???

Help and many thanks.

io -

eBay? Nooop

Just google it. There are some shops delivering rare iPod parts.

Jose Pacio -

how do I know to fix it if it doesn't turn on and there is no sound or light that goes on when charger plug-ins in ipod?

Janice Ward -

step 6: After a bit of wiggling, we manage to pry the display assembly up from the rear case? you mean after alot of wiggling/prying "thank god i didnt break something" holy $@$* the thing finally pryed up... omg!

Phill Chauvin -

Since its soldered to the board ,do I have to buy a new board to replace my headphone jack ?.

Pablo Figueroa -

Please help, the 3.5 mm are stuck inside headphone jack! How can I remove???

Davi -

There are MANY steps and details missing in this teardown.

Era -

When will people learn that teardowns are not repair guides

Duck -

LCD is a wreck.

Zechariah Morrell -

Has anyone figured out what the 75203 23017 chip is? I have an iPod here that has that chip get flaming hot as soon as you connect to a charger. Device doesn't turn on and the battery is sitting at .25V. I'm hoping I can find a donor board to try and swap it out but I have no idea if that will fix the issue.


Thanks guys
