Sure you can buy a $50 BT adapter and plug it into the dock connector. But what if you wanted an integrated, OEM-like solution? Something that on the outside would look like it came from the factory, like Apple should have done?

Step 1: Materials and Tools
Small Phillips Driver
Small Flat Screw Driver
Plastic iPod Opening Tool
One or two 3mm LEDs
Xacto Knife or Razor Blade
Compact Flash to 1.8" ZIF IDE adapter. Get it from Tarkan
Fully ATA compatible Compact Flash Card (2Gb min). I've had good luck with Transcend, Sandisk and Adata but others may work as well.
5th Generation iPod Video. If you use an iPod with a bad drive, just make sure that the unit is otherwise fully functional.
Drill and small drill bit (optional)
Bluetooth headphones (A2DP)
Universal Bluetooth Adapter*
Step 2: Opening Your iPod
Before you get started, know that there is a good chance that you will completely brick your iPod if you don't know what you're doing! Make sure you are comfortable with the complete disassembly of your iPod. Don't come crying to me when you screw up and break it!
Although this is a "how to", you still need to figure out a few things on your own. If you are not comfortable with complex electronics, don't try this!
There are literally hundreds of DIY guides and tutorials on how to properly open up your iPod, so I won't go into it here. I will assume that if you're actually willing to do this hack to your iPod you already know or can easily figure out how to open it up. Just use a plastic tool and take your time.
Be careful, when you finally pry it open the two halves will still be connected via the battery ribbon cable. Disconnect the battery ribbon cable as shown as well as the the headphone jack cable and separate the two halves.
Step 3: Replacing the Hard Drive
If you have not yet changed out your HD with Flash, you can check HERE for instructions to do so.
You can still perform the mod with a 30GB HD, but you will need to use the larger 60/80 GB back cover to allow room for the BT adapter.
As for the CF card itself, you can use any size card from 2GB to 32GB depending on your budget. Remember, it must be fully ATA compliant. I've had good luck with Transcend, Sandisk and Adata but others may work as well.
Anyway, install the card into the adapter but don't install it into the iPod yet.
Step 4: Disassembly
Note: If you want to add a status LED to your project, you will have to continue to completely disassemble your iPod.
Remove the six screws holding the plastic front panel from the metal frame and pull apart.
Remove the logic board from the frame. Be careful with all the sticky tape and be extra careful removing the ground "strap" that wraps around the top of the frame.
Pick a spot along the center rail of the frame and drill a hole just large enough for your 3mm LED. It will hep to use a center punch and a high-speed drill with a sharp bit to do this.
Yes, this will cause your CF assembly to stick up but there should still be enough room in the case. If you kept your HD, then good luck...
Step 5: Preparing the Bluetooth Module
Unlike my 4th Gen BT hack, here I used an older module from Billionton mainly due to its small size. Another difference between the two is that in the Jabra and others like it, you will need to either pair it before you close up the case or allow for a way to access the module's switch.
Prepare the BT module as shown and solder the power and audio terminals to the appropriate locations on the ipod. If you want a status LED, you'll want to solder leads to the SMT LED pads so that you can route your LED to the frame.
Notice that you will likely need to flatten the "bubble" part of the LED to make it fit into the frame without sticking out too much.
Step 6: Reassembly
Once you have wired up the BT module, install the CF adapter. Carefuly thread the BT power, ground, LED and audio leads around the CF adapter and position it as shown. Use a little bit of tape to keep things in place. You might also want to glue down your wires so they don't break off.
The kind of wire you use also makes a big difference. If the wires are too large, you will have trouble closing the case. I used wire wrap wire the first time around but found it was too fragile and kept having to repair broken connections. 28g or 30g "soft" wire works best.
Step 7: Test & Restore
Plug your iPod into the PC using the dock connector. If iTunes does not automatically open up, do so now.
If you're also installing a CF card, iTunes should recognize your iPod and will give you the option to restore the iPod to its original settings. Click OK and wait for it to finish. The pictures below show you what to expect during the restore process.
If you're keeping your HD or have already gone through the restore process, go ahead and test out the BT functionality: Turn on your headphones and set to pairing mode. Turn on your iPod, make sure the LED status light is on. Play a song on the iPod and pair with the headphones. The pairing process will be different for different modules, so see your BT module manual for specifics on this.
Step 8: FAQs
Can I transfer songs wirelessly to my PC using this mod?
Can I control my iPod from my headphones?
How much will it cost?
Will you do the mod for me? I'm willing to pay big bucks.
Do you sell iPods already modified?
