Add INTERNAL Bluetooth Capability To Your iPod 4G

If you're like me, you've often asked yourself why Apple has not added native Bluetooth capability to their iPod line up. Even the iPhone only supports mono Bluetooth!

Sure, there are numerous adapters that plug into the iPod's dock connector to give you wireless music, but they are clunky, they come off easily, can't use them with your case and you have to charge them separately!

So, here is my way to add "native" internal Bluetooth support to your 4G iPod. The same method may be used with other iPod versions, I leave that up to you.

You can also check out my new Bluetooth 5G iPod Video at iPodHackers.net

Required: A steady hand and decent soldering skills.
Oh, and you must be willing to live with the possibility that you will destroy your iPod. I'm not responsible if you screw up and burn up your iPod!

NOTE: I am currently selling this iPod on eBay (item 290199085046) so if you don't feel like doing your own, you can buy this one!

Step 1: What You Need

Materials and tools:

4G iPod
Voltmeter
A few lengths of hook-up wire
Phillips screwdriver
Torx screwdriver
Xacto knife or razor blade
4G 20GB iPod
40GB/60GB iPod metal casing (optional)
Jabra A120S Bluetooth Music Adapter**
Bluetooth stereo headphones (A2DP compatible)

** make sure to pair the adapter to your headphones prior to starting this project, it will make testing much easier in the end**

Note: I am using a 20GB iPod which I have already converted to use Flash memory (see my instructable on how to do this). Removing the original 20GB drive gives me enough room to install the Bluetooth circuit board. If you want to keep your hard drive, you might want to procure a 40GB or 60GB backing for your iPod so that you have enough room.

Has anyone tried bluetooth an old iPhone

Does the iPod's stock earpiece jack still work?

Can the iPod function in disk mode over bluetooth? And be used as a discrete 20gb external wireless hard drive? :D
No, the bluetooth adaptor is wired to the headphones output. Besides, the adaptor probably would only support A2DP, not the OBEX file transfer protocol... Would be handy if it was though!!!
Hey there Doc. I'de imagine to do that would be far more complicated than this hack demonstrates
i have a 4G touch and a jabra BT2080 and i cant listen to music on the BT, they paired fine. thanks
lol "make sure that nothing is smoking" ...nice. DON'T LET THE GENIE OUT!
ahh...we call it the "magic smoke" in my computer repair shop. lol
ah yes, smoke. the secret ingredient that allows all electronics to function. this can easily be proven by noting that once you have let the smoke out of the electronics, it no longer functions. it must be the silicon version of fairy dust.
New machines keep their smoke for a few days, unless they are computers. Old machines keep their (purple) magic smoke for a few decades.

hey. ive been looking all over but to no avail.. i have a motoralo h300 headset and am wondering if i can use it somehow to add bluetooth capabilities to my laptop. i dnt care whether its internal or not. some help would be much appretiated...
Ebay will have mini-usb adapters. I got mine for $2.15 AU with postage.
Hey, I am looking at modding either a 5G or 4G ipod with the compactflash internal ssd and then adding a FM transmitter. My problem is though that I can not find the internal voltage that the ipod runs on anywhere on the internet. I need this because as I have the larger version of both these ipods I wish to add an internal fm transmitter (belkin tunecast 1 or equivalent) for use in the car. I know that most electronic devices run at 5v and was wondering if the ipod has a dc-dc transformer in it to transfer the voltage from the 3.7v lithium cell. Am I right to assume that the dc-dc converter only turn on when the ipod is on? If so I will just use a voltage divider to supply my 3v input for the FM transmitter. Any help would be greatly appreciated. Robert Springer

can you use a bluetooth headset on that?
yeah, but only to listen to music on it. no phone or recorder.

Does anyone know how to do this on a 5G ipod classic?
drad1s5 years ago
I've been thinking about doing this to my ipod before I sell it on ebay, and I was wondering if it would be worth it. How much did yours sell for?
sushiwill5 years ago
everything installed and blinking (no smoke - whew), but I have no idea how to actually pair my headphones with the internal Jabra. Should they automatically pair?

Great job on the hack, gonna try it on a busted 4G iPod I've been keeping for just such a project. One question, does this hack add the control of the BT Headset or just audio transmission? Thanks...
fstedie (author)  macgeist6 years ago
This hack is only for audio transmission. If you want to be able to control the iPod you'll need to find a AVRCP compatible adapter that plugs into the serial (top) of the iPod and hack into that. However, most of them are dock-connector based and there is no practical way to solder into the dock connections (not that I've found anyway). That will be my next hack...
Just curious, any progress on the the AVRCP support mod? Love the mods, followed your guide for the CF mod, works perfectly! Thanks!

could you add an AM/FM radio receiver in there? i have a mini could i put a flash card in, bluetooth, and AM/FM all in? as far as the push button would adding an electronic switch wired to the area on the ipod next to the audio jack with i think three ports, ya know for changing songs using the headphones and what not, anyways could you just turn it on using those ports?

is there a biger Backplate for a Ipod 20GB 4Generation? Can I use the Backplate of the Ipod Photo 4Generation? What is a tiny Bluetooth except the Modul Billionton iPod Mini bluetooth adapter or the jabra A120s? Is there a tiny Modul what automatical connect to a BT Receiver without a switch? The Modul have to pair with code 0000.
You Might be able to find one on ifixit.com.

Do you think the Jabra A120S would pair with another A120S, and act as a transmitter and receiver? So you could listen to music over your car stereos head unit with no wires.

i am really confused. I got an 8GB Transcend flash and the adapter, restored the ipod and pushed music to it through winamp. all is well so far. i tested the jabra while it was in it's case to make sure it worked. i install the jabra like your instructions and it won't turn on. i hold the switch and no blue light. the ipod works fine, voltages are fine, if i unsolder the jabra and hook it back up to it's original battery it works. i am really confused. any help or ideas would be appreciated. i do have an aftermarket ipod battery. were you using the stock battery?
fstedie (author)  pstretz6 years ago
Are you tapping power from my suggested location? You say the voltages are fine, but if it works with the original battery then something is not right. Double check to make sure you're getting the correct positive voltage and if necessary try another spot on the motherboard. Aftermarket battery or not should not matter.
pstretz fstedie6 years ago
i got it to work connecting it to the power connector on the motherboard but still had to hook up the other battery in parallel to get the jabra to start. once it started the first time, i could hold the button down to suspend it and turn it on again without a problem. very strange. seems to work now so i'll see if it continues. very cool mod, thanks again.
pstretz fstedie6 years ago
yeah, i pulling power from C22 and my polarity is correct. I'm reading 4.1V when the iPod is fully charged. i'll try tapping power from the power connector on the motherboard. this is just really wierd.

Hey! Fantastic explaination of everything...cheers for the instructable! One question though...do you think it's possible to apply this same method to a 3G ipod and still keep the hard drive?
fstedie (author)  Quix6 years ago
Only if you can find a larger backplate. Otherwise there is not enough room.

Hey guys, check out the new and improved (but still in development)

ok but you should have used a 16 gb flash to have more space and i love it
you took the words right out of my hand...
