I know this topic has ben discussed plenty of times (I searched), but I can't figure out exactly what I need to purchase and from where in order to get this done. I found a few different ways this has been done.

Basically, I've got an 08 C4S with PCM. I wanted to figure out a very clean way to get both XM radio and Bluetooth (for voice + audio via iPhone). Ideally without anything hanging around externally, with the exception of the necessary antenna.

Can someone point me in the right direction of what I need to get and how to get this done.

I found the thread below, but the purchase link is no longer active.
