So I have an Jaguar S-Typr R 2003 125 000 km. I have the alpine system without the GPS and with the 6 Cd changer in the trunk. Everything is working fine beside the sub that was grinching. So This is when I decided to swap my stereo for a double din kenwood ddx672bh + the sub with an amp kit once For all. I droped my car at an pro stereo installation store. He installed everything with
Correct. That is what he is holding. The S Type uses a fiber optic back bone. The devices are daisy chained off it. If the network is not connected or terminated right then it won't work at all.
Here is what it looks like. Jaguar calls the fiber optic bus the D2B (Domestic Digital Bus). Note the other networks and that all of them are tied together. SCP (Standard Corporate Protocol) this is a Ford corporate thing. CAN (Controller Area Network) this is a widespread industry standard.
Please do some searches. People have done it and it's much easier without navigation. With navigation there not much if anything you can swap out. The double DIN units are very nice and are worlds ahead of the old clunky Jaguar factory system.

The D2B needs to be a LOOP. The network is a unidirectional 'ring'. The head unit sends a '2 blink' signal on one line to check for 'loop continuity' and needs to get the '2 blink' back on the other line.
The D2B is NOT a WIRE. It is BLACK OPTIC FIBER.
There is an electrical harness that is part of the D2B but the connector in the pic is the BOF.
There is plenty of info on the D2B. I uploaded some training guides on the Jaguar networks to large file areas in the subsections.
Go reading previous posts. No, you don't bypass it.
You mean my first post? This is where I learned about the d2b. Now i need to know how to fix this d2b problem. I need straigjt website or the wire converter or whatever. I dobt understand if I need to buy something like the gateway 500??? Thanks

Thanks for the extra info. So just to be clear mine is not a D2B? It's BOF? I'n New to this forums so subsections is something I don't know. Is there a picture or video of how to fix this? Is it something that I Have to buy? Thanks

Just wondering ... So is my problem means that the technician didn't connect the wire or it's because it's missing another harness to terminate the job? Thanks
Previous as in ones others have posted over the last years.
D2B is sent over the BOF.
Wow in the last year ! There is like 200k pages probably. If you have a straight link URL it would be better (straight explanation or diagram or pic or parts) It's annoying this d2b *hit. But thanks anyways
D2B to ISO converter for aftermarket sub+amp+double din???
I have a stype R 2003 with alpine system but without the gps and 6 CD CHANGER in the boot. I bought an afyermarket double din with and aftermarket amp and sub. My technician installed everything and said that the sound comes for 2-3 sec and stops. He double checked and he found the fiber optic D2B a.k.a "BOF" as the pic above. What shoud he do now. He never seen that in his last 10 years.
DO I NEED A D2B TO ISO CONVERTER FOR THE SPEAKERS ??
Alright slimali, stop posting the same question in multiple threads, one thread only please. I've deleted your other posts which are cut/paste from this thread. No more!
The factory 2003-2007 S-Type audio system (also the X-Type and X350 XJ) uses the D2B fiber optic for transferring audio data between modules.
There are NO aftermarket head units that use D2B, and very little if any other components that can be incorporated into a D2B network. D2B was only used by Mercedes and Jaguar, no-one else. And Merc dropped it after only a couple of years so there is nobody supporting this anymore.
There is no such thing as a D2B to ISO converter.
You have no possibility to keep the original Jaguar amplifier, CD changer or any other modules that are on the D2B network (phone, voice, touchscreen, etc) if you go to an aftermarket head unit.
The Jaguar radio (the part with the volume knob on it) is the master of the network, if you remove this then nothing else will work.
Your audio installer needs to make a COMPLETELY NEW installation if you are changing to an aftermarket head unit, none of the D2B modules will work for you.
However you are lucky as the S-Types actually have two sets of speaker wiring in them from the factory. The Premium system which uses an external amplifier on the D2B network. And the Base system which has no external amplifier and the speakers are powered directly from the head unit.
You will need to remove the door card panels and swap the wires over to the speakers in the doors, then you will be able to use the factory wiring for the base sound system, there will be an unused connector in the dash which is for the speakers that are driven directly from the head unit.
You need to get hold of the wiring diagrams for your car (download JTIS, search for it here on the forum) this will help you or your guy figure it out.
Just one last thing to add, if your guy has no idea what I fiber optic network is then maybe you need to find a better guy...

Sorry about that. New to this forum, thought the post goes far away after a day or tow (like an adds page). Thanks alot for your clear reply. Now I completly understand. But just one last thing to really really clearified. I don't want to use any of the factory system beside the speakers that I want to keep. That's why the sound works for only 2-3 sec. I have my own aftermarket :amp, sub and double din. So basically the optic wire will just be there hanging doing nothing? And i will need to rewire from my originals speakers to my head unit (double din) like the car diagrams ? Thanks alot for the info.

Is it the Audio Unit on the diagrams? We need to rewire from there ? Thanks again you were really helpful.
...if your guy has no idea what I fiber optic network is then maybe you need to find a better guy...
I totally second that.
However, none of the replies at the moment has paid attention, to a detail, what was written: there is sound for 2...3 seconds. That means the technition did not totally fail. The question now is: What prevents his aftermarket head to drive the speakers or what prevents the speakers to receive the output signals?
I do not have a convincing answer. I only can speculate. I had a look at the Kenwood manual and saw that the head unit has several input ports. One of them may be not connected as it should and an automatic mute may be the result. Another option would be that the ignition power he used is switched off by the centrakl control module, because the D2B communication is now disturbed (he opened the chain). In this case Jaguar would need to deactivate D2B completely.
Finally he could have been trapped by the fact that S-Type electrical units often have life power and a switched ground.
No sound after installing new stereo and sub !!!
Thanks I will try searching or even finding on another post
