Bluetooth

Hi

I am trying to add Bluetooth to an ipod video 30gb 5th gen 5.5 late (2006).

The parts I am ordering are from China:

Transparent Front,Thick back case with a headphone jack and hold button included,+ a 1900mAh Battery.

the site above is for is for reference, they used a Blutooth module.

Now my question is how can I use an arduino piece with Bluetooth. To upgrade the ipod in a more modern and clean Mod.

Iam open to any suggestions, "and lot of help please".As well as how to solder,what goes were,and how.
I dont want to mess up my mother board. If someone has photos of sqematics. much appreciated.
I figure if I do this mod for my ipod it should have bluetooth, so I can connect my Shure headphones.

If i go this far why not go all the way!!! right. + Ive been wanting to learn this this for a while now.

As well as when i complete the project i will post pictures and the knowledge will be passed on for feature tinkeres like my self.

I thank you all for any info.For my first arduino project.
