So you don't have a screen that allows you to add new or existing accessories? Strange. You can change it in the CCF but I can't for the life of me recall the name. It could be something like audio or accessory and then from the drop down options you can see iPOD.USB then enable it. I know it isn't named iPod or USB on the CCF list itself (even though there are files labeled USB, it isn't those). I sorted CCF by alpha order and a friend I was with spotted it. Sorry, memory is toast anymore.
@Sean W that's right, I can't see that screen. Unless I'm just looking in the wrong area? I'm self taught over about an hour of carefully prodding around.
There was something along the lines that said "USB and iPod through internal module" which I did enable, but nothing changed on my infotainment system.
I'm hoping to get it all sorted so I can get the Mr12Volt system!
Okay, update. I've found the supposed option, Acessory USB Unit. I've tried all of the options listed, but still don't see Portable Audio in my audio screen. Just FM/AM, CD and (recently enabled) AUX.
Anyone that's had to enable the USB/iPod function, do you remember which line and what value you had to give it to enable it?
OK guys, hopefully we can shed some light here. This is my You Tube video explaining how to add Mr.12 Volt to your US 07-08 model cars. There id No need to obtain a 40 pin head unit any longer. Mr. 12 Volt now provides a 40 pin to 30 pin video conveter ribbon.
Sean, I received a PM saying they emailed Mr12V and they do not have the adapter for the 08-09.
But it still lists on their website.

Logan, I posted a reply to this same question here (https://www.jaguarforums.com/forum/x...2/#post2859507). See post #13 about which SDD line item you need to activate and my update in post #15 stating that Mr12Volt now comes with a 40-pin to 30-pin adapter for the 4.2 liter X150s. Originally, Mr12Volt only worked with 5.0 liter model X150s that had the newer 40-pin cable for the touchscreen. The 4.2 liter X150s have a 30-pin cable. You might want to wait to purchase the Mr12Volt until you can successfully use SDD to activate the Portable Audio screen so it appears as below with USB and iPod touch buttons.

I have a number of tabs open on this topic, and your post has certainly helped me out this far. I've actually followed most of your guide in the "activation and installation of rear park assist camera" post.
I have SDD, I've successfully enabled AUX, I've also got Rhys' seed generator for engineering mode - these things all work great. I've correctly identified the line item required, named Accessory USB Unit.
The problem is there's 7 different options ranging from disabled, to just USB, just iPod, USB & iPod and then the same options repeated but saying "for integrated audio module"
I'm asking which option do I need to have enabled? I've tried both versions of "USB & iPod" as well as just USB, but there were no changes to my infotainment system.
One difference I have noticed is that in your post your CCF seems to be in an XML file, whist I'm doing my changes on "Car Configuration Management – Current Vehicle Car Configuration Modification"

Is there a difference?
"for integrated audio module" is what you want. That's what the module is referred to. I just couldn't recall the naming convention. Select it and then let the software download from the computer files. I did this some years ago when I actually installed an AUU (iPod) set up in my 07. I activated it through the CCF.
My video shows the latest approach but as far as I can tell, you're the first who didn't have that option to add it as an accessory. So do it the old fashioned way and use the CCF. You're not going to brick anything. It will show up on the touch screen or it won't. Pics would be helpful.
Also, yes Kurt C downloaded his files to excel but that's not a CCF view and not part of SDD.

I’m Siriusly laughing my *** off at the comments.
ok, so just to clarify. If one goes into SDD, has engineering mode (for the ones that require it) and turns on all the options. AUX, integrated audio and if there is a third? Bluetooth or whatever….
You won’t brick the head unit? If the hardware or whatever doesn’t support it, the option just won’t work or at worst (like I saw with one backup camera mod setup) will show a blank screen?

I don't think you can answer that with a yes or no. SDD supports hundreds of models and model years. I'll try to sum up without steering this thread further south.
Enabling AUX doesn't require engineering mode. It's in accessory add on's.
Bluetooth in our X150's only relates to cell phone calls. I've never modified the BT module via CCF options and don't even know if there are any. Pretty sure it's going to be equipped or not equipped. If that module failed, as with changing out any module, you would enter from the Replace/Add and replace while following instructions using SDD Best Practices.
With regard to turning on the integrated audio, it will either work or it won't (nothing will change). None of the stand alone USB selections that appear in the CCF apply to the X150 to my knowledge.
My approach is to assume most changes to the car configuration file have consequences. I know from experience that this particular one the OP is trying to enable doesn't. Hope this helps.

...I'm asking which option do I need to have enabled?...
@LoganW and @Circumnavigator , I will try to resolve some of the confusion. As my 2009 XKR came equipped with the USB/iPod accessory, ‘Portable audio’ was already a button below the CD button on my touchscreen. When I enabled AUX using SDD, an ‘AUX ‘button appeared next to the ‘USB’ and ‘iPod’ buttons under the ‘Portable audio’ selection. Logan, if you enabled AUX before the USB/iPod accessory, then your ‘AUX’ button may be appearing on the left-hand side below the ‘CD’ button. I believe I’ve seen some pictures in some threads here showing this alternate location of the AUX button. If so, I don’t know how to resolve that, but I’d try disabling AUX, then enabling the ‘Accessory USB unit’ first to get the ‘Portable audio’ button appearing as in my OEM location. Then, secondly enabling AUX might make all the buttons appear as on my screen. Another item I do not know is if the ‘Accessory USB unit’ will actually become enabled without a physical USB/iPod module to detect. It may need that as part of the configuration process; although, I kind of doubt this as I previously enabled the ‘Heated steering’ option on my touchscreen and it would turn red when pressed, but nothing happened since I don’t have that type of steering wheel fitted.
Logan, as to the ‘Accessory USB unit’ parameter options in SDD, SeanW was correct in relaying that I had made an Excel (XML) file of all the available parameters in SDD v130. It is much quicker to scroll through Excel to find parameters and their settings than in SDD. My list is available in both Excel and PDF formats at Car Configuration Personalization Parameters in SDD v130.
To more fully answer your question, I went in to SDD today so I could show you how my OEM ‘Accessory USB unit’ parameter is set. The first picture below shows the last six of seven options available and the one in blue is how the factory has it set. The second picture shows the full name of the factory-set option when the mouse is hovered over it.
.
.
.
And SeanW correctly point out that you do not need Engineering Mode to enable AUX. It’s an option in the Service Functions as shown below. But you do need to go into Engineering Mode and then the Service Function called, ‘Car Configuration Management – Current Vehicle Car Configuration Modification’, to enable the ‘Accessory USB unit’ as shown in the pictures above.
I know the thread is for 07 and up thought we had it all sorted out, 07 and 08-09.
Until last night, my understanding was that installing the ACM and usb/iPod add on was not necessary as the Mr12v unit bypasses this (per @Sean W I think).
So all I needed was the $500 unit from Mr12v with the 40->30 pin ribbon cable and SDD engineering mode to enable AUX.
But then in a FB Jag group, I see a post from Liam Biggs who does mobile installs in England.
He says the usb/iPod addin (which means a pricey used ACM) is required.
I’m going to get to the bottom of this and post what will hopefully be the be all end all Sticky on this subject for 07 and 08-09 MYs.
Here is the convo with Liam:

@Circumnavigator , maybe Mr12Volt's documentation will help you put things to rest. Attached at the bottom of this post is their 'Mr12Volt P2000-XF09MM User Guide' and on page 2 it states the following:
.
‘Factory USB module under the passenger seat must be disabled with bypass connector supplied in the package.’
.
Then at about 7:30 minutes, they show how to connect their fiber optic cable to your infotainment head unit. So, I’d check to see if your head unit has all the connectors they connect to.
.
.
It may be the reason they state the USB module must be installed is to ensure the USB/iPod accessory has been enabled for your infotainment system (which may be done independently using SDD). That same User Guide states, ‘Mr12volt is selected through Portable Audio > USB features of the head unit’, and their website shows the following picture.
.
.
Since Mr12Volt is very good with technical support, contact them and tell them that your 2008 does not have the physical USB module installed. And then ask if it will work to simply enable the USB accessory using SDD or do you need to install and enable a USB module only to later bypass it per their instructions. It may be best to contact Mr12Volt directly with your questions.
So I watched the first minute of the Mr12Volt installation video and stuck half of my huge *** into the trunk, looking for this:
Which AI identifies as the USB module? So you can use the loop back bypass in the kit.
So with flashlight and phone in hand, I open the access panel (remember I have a vert, the video is def a coupe).
And all I see is this, with three straps around it. Strangely the straps are not removable!?!?
I felt around 2 of them and there was no edge.
Ill assume this is the top hydraulic pump covered in some foam protection or noise insulation.
Could the box in the vid be behind that? Umm not probable if it is the pump. Wouldn’t be room.
But before I can find out, I need to know how to get the straps and then that cover off.

Thing is, your car doesn't HAVE the USB module. They are only in the 5.0 cars.
