Maybe someone here know this. I have a 2010 E200 estate with the Audio 50 APS audio system. This has a 5.8 inch screen. I am installing an android-auto-box behind the screen soon, and I saw that on that android-box you can set the screen size (5.8 or 7 inch). My friend also has a 7 inch screen. So I started searching.
I have this screen, 5.8 inch, part number A212 900 49 00:
And then I also bought a very cheap 7 inch screen, part number A212 900 50 00:
Before I bought it, I checked the connections on the rear, which are exactly the same for both screens:
I connected it, turned on the radio, but only the backlight turned on.
I would imagine that the screen could work as it has the same connections. But also maybe it's not that simple?
Does anybody know that what I tried is possible? Maybe my cheap bigger screen is just broken?
Dear, can you show me where option in variant coding to change display from 5.8" to 7" screen. I try to find but found nothing.
Thanks
I access Variant coding very simply from Launch scanner, other ppl do coding through Vediamo - I don't know how many screen sizes are up for selection. My original display module has no issue to all my attention.
I now have the bigger screen installed. I have configured the android box to use the bigger screen by setting some jumper-connectors (you can toggle between the big or the small screen). But now when I need to be in the original interface, the screen is just black. I don't mind very much because I only use the AUX input from the original system. I don't have CD's anymore, navigation is google maps via the android box and my radio and music is all done via the android auto box.
But now I have an issue where my clock is exactly 1 hour off, so I now do need to go into the original system interface, so I need to plug the small screen back in to do the changes, and thén plug the big screen back in.
I don't like to buy a scan tool just to set the screen size to the one I want. If this can be changed in the NTG engineering menu, I would very much like to know which option I need to change, and to what setting it needs to be.
@CaliBenzDriver Yes I understand, but for me to be able to see the normal UI, I need to place back the small screen. It would be great if I can tell my head-unit that it needs to drive the bigger screen instead of the smaller one.
Do you know the exact setting which needs to be changed in the engineering menu, or not?

Audio50 NTG4 has no any settings for screen resolution. You can only use the small screen if you want to keep the Audio50, or you can install a very cheap and crappy Android immense display.
Any other options here for Audio 50 is only paid advertising.

You are searching for the option to switch NTG Display as "Android extension" instead of "stock Display".
NTG HU can not address any data into your Android screen. It's an entirely separate replacement module.
With an Android screen, the stock display is disabled, NTG is headless.
The "Engineering Mode" interface is useless without a display. You can only program your NTG through the VARIANT Coding interface.
Your "Time-clock DST" settings can't be accessed from there either.
Hope this helps settle your issue.

No I'm sorry, that's not what I mean.
I have an android auto box in between the head unit and the screen, so I can have android auto in my car
What I purely mean, (and keep anything android out of it haha) I have an AUDIO 50 APS system with the standard small 5.8 inch screen. I want to upgrade the screen to the 7 inch version with the higher resolution. When you have the COMAND system, you also have this big 7 inch screen. The connections on the back of both small and big screen are the same (see pictures on the top post), but when I connect the 7 inch screen, I get no image. The backlight turns on but no image.
And now the question, is there any way to configure the AUDIO 50 APS head unit, so that it drives the big 7 inch screen?

I see... you are trying to upgrade the 5.8" stock display with a 7" display.
This is not "plug n play" upgrade but you can test getting the new display module coded into the system.
Some of this might work if your new display is backward compatible. What are the odds...

The Android box should be between Radio and display. Try to find out if your box can support a higher resolution. Usually those boxes has some DIP switches for this kind of settings or some accept a USB with a config file for changing the resolution.
Your Radio doesn't have any options to increase the resolution, but this could be not relevant if your box is installed.
Yes right now I have the android box installed between the head unit and the display and indeed, I have set the switches on the android auto box so the android auto box drives the bigger screen. So I have android auto working on the bigger screen. In android auto I can use google maps, spotify, play radio via a radio app and I can also connect a usb drive to play MP3's. Meanwhile my headunit is just set to the AUX input on which the android box is connected. I don't use any functionality of the original system anymore exept the AUX input. When you shut down the android box, normally the original interface of the head unit is displayed again but because I have the big screen installed, the screen is then only black.
Now I need to set the time on the instrument cluster clock, and that is normally done on the headunit but now I have to temporarily put back the small screen and set the time, and then put the big screen back again.
The Audio 50 should be connected to the box as well, the Output Video cable, if box has this input.
As you say the Aux Input (into) the Audio 50.... it's just an input ( more likely to pass the Audio from box to car speakers), being an input, it can't output anything.
Audio50 NTG4 has no any settings for screen resolution. You can only use the small screen if you want to keep the Audio50, or you can install a very cheap and crappy Android immense display.

Hi, My is Audio 20 NTG4.5 HU entry, so can I change setting for screen resolution?
Thanks.

Yes yes yes I know, I have the android auto box connected properly. When I switch the big screen for the small screen I can see the mercedes audio 50 interface just fine.
I will just switch the big screen for the small screen when I want to adjust something in the audio 50 interface and afterwards switch back again. I'm giving up searching for a solution for this.
Yeah, I've had the 50 screen with NTG4.0 in my 2022 S580 for a bit now, and it's a night and day difference from the older 8.4 screen - the graphics are so much smoother and responsive. I've heard the software is still a work in progress, though, so hopefully they'll keep updating it to take full advantage of the hardware.
