Retrofit of 12/13 Infotainment into a 10/11 vehicle project
Although i already have a couple of unfinished side projects, this particular conversion project is something i now need to do not only for our ongoing software development but now that i own a 2010 vehicle, is something i would really also like to do as an upgrade on it.
All assuming that it is ultimately possible of course.
To start i have needed to figure out the core elements of both systems and identify how they are different and so what might be involved in retrofitting the latter to an earlier vehicle.
The 2010/11 Infotainment system is actually not too unlike the Pre 2010 one.
The heart of the system is still the same Integrated Head Unit (IHU) that provided the Gateway from the CAN BUS to the MOST BUS, Used alone in a FFRR, with controls via the Touch screen, Piggy backed on top of the Head unit in a D3 / matching year sport with controls via the front panel, and in a 2010/11 D4 and matching year Sport it sits on top of the CD mechanism and has a seperate control panel on the CAN BUS.
The only real other difference in the 2010/11 vehicles is that the DVD based Nav computer that lived under the Passenger seat has been ditched and sat nav functionality incorporated in a new HDD based Screen unit. The one with the curved stack of on screen buttons.
Otherwise all the other MOST BUS items like the 300 or 600 watt Amp under the drivers seat, Phone and so on are pretty much the same and are interchangable with eariler pre 2010 ones.
In a 2012/13 Vehicle the infotainment system has however been completely re worked.
To start off with the screen has again been replaced with one that is now the CAN to MOST gateway, but no longer has the HDD and Sat Nav functionality built in.
This has now been moved to a new all in one Most Bus connected unit called the Integrated Audio Module (IAM). It replces and incorporates the CD Mechanism, can come with or without HDD and sat Nav capability and also incorporates phone, DAB and radio functionality.
The Amp used is also physically very different and comes in 600 or 1200 watt variants. It has also been re located from under the drivers seat to in the rear quarter panel. I also suspect that any other item that is fitted on the Most Bus is also different at least electronically and cannot be interchanged.
Progress so far.
I have researched all the power, CAN, Mic, Aux and some other odd connectivity from the two systems and so far see no real problem
Fortunatley have a full 2011 bench test rig set up and have sucessfully managed to disconnect the old IHU, screen and all other items it uses and using a later facia loom only managed to graft a newer type Dual view screen and IAM with Nav and HDD onto it and have it mainly working and at least diagnostically communicating.
I just took delivery of a 1200 watt Amp and will be adding this shortly and also believe i have a TV tuner that is compatible. If anyone can help me locate a 2012.2013 RSE unit i would appreciate any help. I already have the newere type head rest screens and touch screen remote
So far, in practice at least, things seem going very well, if this continues then the next stage is to apply this conversion to a real vehicle (mine) and of course fully document and photograph every step involved to share with anyone interested in doing the same.

Yea, pretty much
I regard myself as pretty lucky to have that which interests and challenges me and my understanding the most also what i get to do for a living
Having real hands on experience with all the wiring and ECU's we develop diagnostics for really compliments our theoretical knowledge and it is certainly time i moved this up a notch or two.
And i guess it is nice for members to know that i am personally a landy lover at heart and certainly not adverse to picking up some tools and getting my hands dirty

Hello Colin,
Not the same I know - but similar. I have just finished adding full OEM RSE and full surround camera setup to my 2012MY car.
I have access to quite a lot of extra spare components & looms - will send you a pm - just in case anything interests, or is of use/help you
Best regards
Andrew

Colin ,clearly most of what you noted above is another language to me....and I know,and understand the reasons you want to upgrade .... However the '12 system has well documented response issues,and some units are currently going in for exploratory work,I'm just wondering if you might be better hanging on for a short period ? "Better to remain silent and be thought a fool,than to speak out and remove all doubt" ?.....what rubbish...

Hi Andrew,
did the transmitter work fine for the rear then?
did it just wire up an go, I need a FFRR rear passenger transmitter to get mine to wire up

Cheers for your Help Andrew.
I have just replied to your PM
euangibson
Yea, i know all this kinda stuff can seem a bit much for many, but hopefully i can figure all the tech bits out and simply detail / demonstrate what needs to be done to achieve this modification in a simple enough form that others can then follow.
Unfortunately vehicle duties here in Cyprus are so expensive, this prohibits my buying a 2012 vehicle, so the next best thing is a 2010 vehicle that i upgrade to to 2012 specs, which also has the benefit of meaning i gain some real hands on experience with the 2010 and 2012 systems.
Yep i know there are some response issues with the 2012 V the 2013 System that LR currently seem clueless about the real cause of.
All the more reason for me to get hands on with a 2012 System

Hi Rob,
All done & working fine - thanks (although I couldn't save the cable - had to buy a new one).
Thanks

Good luck...then all I need to do is persuade the family that a road trip to Cyprus is a good idea,and you can fix mine ! ....thanks for the response "Better to remain silent and be thought a fool,than to speak out and remove all doubt" ?.....what rubbish...

Hi Colin
Did you manage to get the Touchscreen, IAM and amplifier from 2012 D4 to work together and recognised in settings of CCF? Having a problem with my 'graft in' because I can only select and view the settings for Touchscreen not IAM or Amp.
Thanks
Jack

Forgot to mention that Touchscreen was found under:- Front Control Interface B (Type 5)
Tried to find IAM under:- Integrated Head Unit 4 (Type 5) - but nothing there
and Amp under:- Audio amplifier module 3 (Type 5) but as I am using a Logic 7 from D3 guess it will not be there anyway?

Thanks

Hiya Jack
As i stated
Quote:
this particular conversion project is something i now need to do not only for our ongoing software development but now that i own a 2010 vehicle, is something i would really also like to do as an upgrade
This means that we are still developing coverage for the infotainment items fitted in the 2012 vehicles, and learning all the details we need to know about what is different and how.
So currently there is no menu option or coverage for the IAM And the Front control interface is actually a Button / control panel
Because the new 2012 Touch Screen is now the Gateway between the CAN BUS and the MOST BUS and is therefore the MOST BUS master, it seems that you can only fit MOST BUS ECU's from the 2012 vehicles with the same screen and an IAM.
This would of course preclude the use of a Logic 7 Amp from a D3 and when we tried a known good one of these ourselves on our Screen and IAM pair which we have working, the MOST BUS actually stopped Working until we removed it.
Fortunately i have acquired a rather nice 1200 watt Amp for a 2012 Model, but we have yet to add this as we don't yet have the proper connectors for it.
There is a lot more learning, testing and developing to do yet, but we are surely getting there

Hi Colin,
Thanks for update and I will hang on to the bits I have and try to get hold of a newer premium amp like yours. Looking at your other posts I have found the same problem with all of the amps for sale being Mid-line rather than Logic 7.
The MOST system for the last week has been running with the Touchscreen, IAM and D3 Logic 7 amp fitted with just the 4x4 display, sad I know!
Anyway that was until last night when the screen shut down and just displayed the parking display. The display has been random today and I did wonder if the MOST bus was to blame so it looks like I am getting the same as you have found.
Is there any method I could identify the correct amp for my set up apart from buying new from the dealers?
I am waiting for this to be sorted as well because I did a mates conversion the same as Jack2006 and I have the exact same issues as in there being no menu item for IAM selection in the CCF, we have the phone radio and sat nav working but no cd, or DAB or aux input recognized.. so get your finger out and sort it
