After reading the documented process of adding internal bluetooth to the 4G and the 5G iPods by Fstedie I went about figuring out how to get it to work for the 2G Mini. The final result is a completely unaltered looking Mini that has A2DP stereo bluetooth. The stock headphone jack continues to work as normal, however the left channel on the bluetooth headphones gets disconnected while a wired headphone is being used.

Soldering gear
This bluetooth adapter. Since this link will probably be dead relatively soon it might pose a problem for those of you trying to do this mod; the item is listed as a generic bluetooth adapter but in the manual it is revealed to be the BTAV101 manufactured by Flaircomm.
A few lengths of thin wire. I harvested my wires from an old parallel cable.

So, let's get on with it.

UPDATE:- After getting it all together and trying it out it turns out that the mini's case doesn't allow the transmitter to work nearly as far as it normally would. Extending the antenna out of the case doesn't help. It works up to about 6 feet when out of my pocket but it starts getting choppy while in my right pocket. Not sure what's causing the interference in my pocket, but the problem disappears while in my left pocket.

Step 1: Breaking It Down

So this is pretty straightforward. We need to get everything down bare so we can work with it. For the 2G iPod Mini the tear down is relatively easy. The guys over at ifixit.com have a great guide on how to get it down to where we need it. As for the bluetooth dongle, all we need to do is slide a flathead into the crack between the two halves and GENTLY pry it open. We dont want to stab right through it and risk damaging any of the internals. Unfortunately I'm writing this post teardown so I don't have any pictures but it's dead easy. The usb port on the adapter is too big to fit into the iPod and needs to be removed, I removed it by gently prying it off with a pair of pliers.
 How does this affect battery life? Do you happen to know the battery life on the bluetooth transmitter? I'm interested in doing this.
That is awesome
