My very first post here. I just registered to provide the info on how I made it work on my GLE350 from Aug 2015 (Model 2016). Thanks to this post I started looking online everywhere and also into WIS and found the following info in the AZ82.60-P-0028NKM doc (See attachments).
It takes roughly an hour although some dealers would like to get little bit more

STEP 1. Install the new multimedia interface A1728202000 (done by me in 5min, I used a very short knife to detach the old interface)
STEP 2. The main thing is adding ALL three codes to vedoc (some dealers only add 14U and wonder why it is not working):
Code 14U (Smartphone integration data card package)
Code 16U (Smartphone integration Carplay)
Code 17U (Smartphone integration Google Automotive Link)
Attach note "Smartphone integration package retrofitted as per AZ82.60-P-0028NKM" under field organization texts to DG 82
This can be done only be the dealer and needs an approval from Germany. So it takes about 2-5 days.
STEP 3. After the approval, ask the dealer to update the software of the head unit

Note: Use only a very good cable. After I got the update I tried it with my phone and the connection was breaking the whole time. I thought I just wasted time and money, but on some other place I read to buy an expensive cable and it is now super stable. I like it now since it is very well integrated. (Thinking of buying motorola ma1 and going completely wireless. I do not know if it will work as good as with the cable.)

Some more info:
I struggled finding a dealer because even after providing the above documents, many dealers refused to do it. Thankfully where I live there are many around so I found 2 that can do it.
I found a used part A1728202000 on ebay. Mercedes is actually selling A2468203800 which includes A1728202000 + two cables as a kit. But I do not need the cables since there is no USB-C. Mercedes discounted the part recently and there are very few in stock (something like 15? in the whole country).
If you have the early 2016 that has only Apple Carplay and not Android Auto, it can be done by adding the above 17U and updating the software.
The very first GLE 350 head units in 2015 as well as the ones in the model 2017 has the exact same HW A1669011403. Only the preinstalled software is different and that is why they have different part numbers. So no hardware obstacles.
Some folks online state that you do not even need to replace the multimedia interface. It should work with the old on. The new box just have a smartphone picture on one of the USBs to show you where to plug it in. But I have not verified it yet because somehow the trick with the knife is not working on my new box and I could not replace it to try it.

Hope the above can help. Thanks for all your info.

 

For GLE ( 166 and 292) all Units with SA Code 531 ( Comand Online) is compatible with CArplay and Android Auto, on older models a simple software update and a coding is enough.
If has SA Code 522, then is almost rare to be compatible with any of Phone Integration Package.

Only need to check Data Card from VIN decoder

 

For those who wish to update, feel free to msg

 

[QUOTE=Orlando Lopez;9100515]reng reng DId you went to official MB dealership and they mess up the interior lights trying to solve your broken Carplay?

 

[QUOTE=trigital;9100523][QUOTE=Orlando Lopez;9100515]reng rengDid you go to MB's official dealership and they messed up the internal lights trying to fix your broken Carplay? ] Yes, trying to fix the carplay spoiled the interior lights, it doesn't even turn on the light when it opens the door, nor the lights on the dashboard or the doors, I'm referring to the lights we can change color

Indeed your car received from the dealership the factory coding only for your Comand.

Your car had Ambient light with colours retrofitted?

 

Yes I had

 

What you think, it won't be better for me to buy this https://www.obdexpress.co.uk/wholesa...-doip-ssd.html, and then you help me

 

Pors What part of Spain is you in, if not too far could I go?

 

reng I'm so sorry, after all the led light from inside is active, was the ceiling button off, 🙈 I'm just missing the carplay.

 

No need to buy this, as is expensive and can't do anything more than 10$ E-net interface, especially if you are not an workshop

The flashing/coding can be done remotely.

I can help you for free.

 

Thank you very much, what does it take?

 

A decent Windows 11 laptop and buy from AliExpress an Openport and E-net interfaces

 

you say I need an interface and internet, I apologize, but the translator sometimes exchanges the words

 

Peço desculpa mas o tradutor as vezes troca as palavras, você diz que preciso de um interface e de Internet, é isso?

This is very helpful (and directly applicable to my used 2016 model, which I purchased not long ago to replace my 2014 GL350 BlueTEC).
