My homebrew D2B aux input adapter
Early stage, I'm able to play music via the aux in. The control is via PC at the moment, once I iron-out the issues would move it to a standalone micro-controller.
It should work with my Jag setup as well. I'll try it in the next few days.

In a few months maybe. For the Jag the most difficult part to obtain is the optical connector. It's made by TYCO/AMP, but it's practically unobtainium as it's covered by some weird licensing restrictions.
I'm working on a model that can be 3d printed. I have some success, however I put that on hold until I finish the software for the device.
For the next version the plan it to be able to connect your phone via bluetooth; those are only plans though ;-)

Here it is installed.
The bluetooth dongle is not very happy in the trunk. The phone works great if I put it in the passenger seat, but starts to hickup if I get it in the drivers seat.
I'll get a USB extension cable and put the bluetooth dongle on the back shelf, hopefully that would help.
PS: the box is covered in copper tape, not painted "gold" ;-)

If you look at the first picture in post #7, the device contains 2 boards. The green board is a raspberry pi A+, which handles the bluetooth streaming with a little software that I wrote. From the PI the audio goes over the second board that does the D2B protocol handling. The second board is all my contraption. The audio is digital all the way. The only quality loss is the bluetooth encoding, but that is unavoidable.

Really interested in doing something similar - can you share anything regarding the D2B protocol handling? - I was hoping to manage most of this through the Pi - bespoke boards is over my head. BTW I though I'd salvage optical connector from an existing CD changer - is that going to work? - cheers in advance for any pointers / advice you can share

The chip that handles the optical bus is OCC8001 codename Conan. To get information how to hook it up google for "be3300 schematics" - this is a head unit for Mercedes Benz. It uses the same optical bus, just different optical connectors.
I'm attaching the pinout of the flat cable of the cd-changer optical board. It it she same cable for Mercedes or Jaguar - again the optical board only difference is the fiber optic connector.

veffremov,
Wow - You are a patient person, that's great. I just picked up a 2008 Xj8-L, and am frustrated by the lack of reasonably priced options. While I am not certain what market demand might be, there is a demand, and while I speak for myself, I could see spending $500 for kit to connect usb, and bluetooth to my factory controls....
Great project, wish I had your knowledge and patience, but I do not ...
Do you have any plans to sell a kit?
