Hello!
now I have a friend in the process of change. He has bought the 7 "screen and it comes on 3/11.
Everything we have investigated ElsaWin is no need to change anything else, cables or coding. Plug & play dude!
I will update with the progress he made
I seriously doubt it too, even for the backup camera, you'll still need to code the module to display it on 5.8" or 7" screen properly. The standard MMI wouldn't display correctly on the 7" I think. I went aftermarket on the screen, everything gets blown up on the 7" so basically, same graphics, just bigger... But that's with a aftermarket pass through module with added functions as well.
I seem to recall @DJAlix detailing this in a few threads before. I think the new screen requires a new MMI module in the glovebox as the video cables differ.
Now I've mentioned his name though, I'm sure he'll appear in mere moments like some digital genie to correct me. ;-)

I compared in ElsaWin the cable between MMI module and MMI screen for "MMI High" and "MMI Low" and they are the same.
Please feel free to add any information. We have one week yet to receive the screen and try it!
thanks in advance

Even if they use the same connectors I doubt it will work. Think of a PC: you can get a monitor with a 640x480 display using the same connector as a 1920x1080 display. It doesn't mean by plugging an HD monitor onto your 486 you'll get HD coming out

Whilst what you say is true for legacy systems and analog displays, use a digital medium (like HDMI or DisplayPort) and a digital display, a modern OS will work out the native resolution with no input from the user.
So in theory, it "could" work, not saying it will mind.
I agree, I was merely trying to get across that "just because it fits doesn't meant it will work" ;-)
Anyway DVI/HDMI/etc are an ISO standard. I doubt Audi (or any other OEM) are using any interfaces with such standards ;-)

I bet they are, just like laptop manufacturers do, even though they have no need to standardise on the plugs at either end of the cable, the actual protocols used will be HDMI or DisplayPort.

Seeing as this is the only thing that really annoys me on my car having the smaller screen, i would get this done straight away if it's that simple.
I'm sure someone tried this a few years ago and ended up with the display only filling a quarter of the screen area. Can't find the post now, but it'd be interesting to see if anything has changed since.

Of course, I can be wrong.
Please sorry because I post the ElsaWin in Spanish, but you can see in the photos that this is the same connectors in High and Low Versions.
And the data cable doesn't have any "chip" or electronics.
Maybe I can need to recoding the module 5F to set the new size of the screen, like anyone says before.

Does at least prove one thing, they are using LVDS, which is a digital display standard

for more in my favor.
I Have cable TV, and I have a TV of 20" and another of 50" in both the signal and the cable (and the source) are identical.
I think the image of the MMI is exactly that.

Changing a low res screen to a hi res in PFL cars will not work unfortunately. The MMI Standard and MMI Techpack use two different video cards. The connections are basically the same but the screens are not interchangeable. Someone already tested this and when connected the hi rez screen would only display static.
Edit1: The person you tested this is a member of the forum and posted the results a while back. A search will turn up the information.
Edit2: There is a coding that was not known at the time which you could always try once you have connected the new screen. Untick this one and see what happens:

Yes I search (and found) several threads about it. Sorry to say that you speak of MMI techpack but in Spain there is no such name.
I explain the current configuration and where we want to go:
MMI1, with connectivity package (basic browser), screen 5.7 "and MMI unit in glove with 2 SD slots
Change the screen only 5.7 "by 7" Advanced browser.
Either way the screen is on the way, in a week we test and I comment the result.
Thank you all!
Another thing, I do not want to advertise, but there is a third-party equipment vendors (there a thread on this subforum) that replaces the screen and does not change the cable. And the multimedia unit added doesn't have graphics card.

Just for future reference here in the UK the systems are know as:
- MMIv1 with 5.5" Screen with 1 or 2 SD Card Slots + AUX or AMI = MMI Standard / MMI Low / MMI SDNav
- MMIv1 with 7" Screen with 2 SD Card Slots + with or without SIM Card Slot + AMI or AMI and USB = MMI TechPack / MMI TechPack w/Connect / MMI High

This won't work,
I know as I've tried.
It will only fill 1/4 of the screen, as said above
The cable isn't the same either, I mean it is the same but you actually need to cut out a notch on the cable connector for it fit onto the new screen

As above, tried it this morning as I missed the screen option in my coding when I upgraded.
Still has four separate screens, left two filled.
You'll need the box at a minimum to upgrade to this.

Hello!
I recently bought a module MMI screen 7 "with reference 8V0857273G to replace my current MMI 5'8".
After making the plug & play properly screen emits image and performs well but looks as it see in the picture.
I need your help, anyone had made this change? Can this be solved with VCDS coding?
King regards

You will need to upgrade your MMI unit from the Low / standard to High / techpack. The video card in the Low / standard unit is not compatible with the 7" screen.Hello!

As stated earlier within this thread, this was tested over a year ago and found to be not possible. The new MMIv2 Low and High units used within the FL 8V cars share the same 7" screen, but the MMIv1 PFL units cannot due to the different internal video cards which they use. It might be possible to change the video card within the MMI but good luck in trying to buy one.

I don't have a screenshot but the coding of the MMI techpack unit with 7" screen is also 01 for Byte 20:Can someone do me a favour?
I need this same screen but in MMI 7"
A screenshot of this will be great
Thanks!

It did work please have a look at this spanish (@FrA1l3 ) artist page on the spanish forum

Just spent some time reading that thread, and the DIY guide that's linked from it. Seems that the screen they are using is from AliExpress and appears to work with the existing MMI. The Android system they appear to have spliced "in-line" with the original MMI unit, plenty of photos showing that they are using MMI on the larger screen, though IMO the resolution simply looks stretched to fit when in MMI (ie still looks low resolution, but a bit blurry). Not yet found how they are switching between MMI and Android though, but have seen that they have modified some settings of the MMI in VCDS to allow the audio passthrough and selection of sources.
Interesting read though.

There are a number of these in-line systems available now, was one on eBay from MTM (not the Tuner) for £350 the other week. Although kinda good none are fully working from what I have seen.

Having dealt with a myriad of Android based headunits in various cars over the years (the latest in a dynavin style unit for an E46 BMW last year), I personally wouldn't go anywhere near one. Great idea in theory, but always utterly garbage in reality.
The fact that they have the larger screen working with the "lower" MMI unit is interesting though.

MMI video out > andriod unit > new screen andriod screen, so it's not really "working" so to speak. The unit and new screen are just compatable, unlike the OEM Audi components.

so, please confirm if I have understand correctly:
if you have installed in 1, is the low resolution MMI Std,
and the the Screen (3) is OEM the 5.8, then
no matter what you install in (2), e.g. Navitouch with the bigger screen, the graphics card of (1) would not be providing a bigger image

Sorry, you are wrong. First you have to understand how the MMI-Screen works with the LVDS connection and then how to interpose (an android) in that connection and how the android processes the image.
In my case, the link that you have put up, the MMI is the basic, the original LVDS cable that leaves the MMI to the screen, connects to the android, where a specialized 1024 (HD) chip is responsible for reprocessing the outgoing image Of the MMI and send it by another new LVDS cable to the new screen, which has 1024 resolution. Nothing to do with the original screen that Audi, either the 5.8 "or the 7"
The android chip, is independent of the operating system, works in parallel. That is, I can hang / break the android OS, and the MMI image will still work perfectly.
That said, the chip re-scans with interpolation the images, but they do not look with sawtooth or pixelated as I think it has been said, if they do not look much better quality menus. Just see the song covers. The only thing that seems not very successful, is the text of the menus, but that is by the type of source that Audi has chosen to visualize.
However, in my profile of the mentioned forum, you have images and videos of the android performance. If you put the images to full screen or videos, and 1080 on youtube you will see the quality it has.
The images uploaded to the forum, are reduced of quality so that they occupy little. If anyone wants good resolution images, they will be delighted. Or videos or whatever you need.
