This is it!
The proper activator for Audi MHS2 systems made by delphi.
It a result of deep system analysis and some good reverse engineering.
The time has come and i have decided to share it!
Now is available free of charge for everyone!

Unlike the leaked version of the activator this one is tested and in use for quite long time now.
You will not loose ability to install custom POI's and for sure it will not cripple your legal function enabling codes.
I cannot guarantee that will work on every MMI out there, but i never had issues ever since i created it back in 2016.
Regardless of what some might say, update of the MMI is not mandatory. This is entirely up to you.
If your MMI is working properly and you have not noticed issues then you can continue using same version.
Believe me, i know these systems inside out.
As you will see bellow the supported versions list is quite long and will only get longer with time!
In case that you do decide to update then subscribe to this topic as i will update it to include software update info and files.

In the archive you will find a manual how to use it.
It is very simple process and you will only need one empty SD card size 8-32GB FAT32 formatted.
After activating the MMI you will be able to use latest navigation maps.

Here is list of supported versions, it was tested on many more but for now i decided to include the following.
If your software is not the support list then send the backup that the activator will make and i will add it. Always make sure you are using the latest version of the activator.
Almost any version out there!
If for some reason you cant get it to work following the manual then its likely that your unit was already patched.
In such case contact me and i will see what i can do about it.

Please have in mind that im doing this in my free time and that means that im not 24/7 available :)

The map of MHS2/MST2(soon to be released) is not installed, you copy map on SD and just insert in the unit. If coding is ok and fecs are shown as valid then map will work.
Simple as that :)

MAP 2022/2023 -> 11.64 GB file on MEGA
MHS2_ER_AU_K0129 -> 2.09 GB file on MEGA
MHS2_ER_AU_K0471 -> 2.53 GB file on MEGA
MHS2_ER_AU_P1242 -> 2.55 GB file on MEGA
MHS2_ER_AU_P2035 -> 2.54 GB file on MEGA

MHS2_US_AU_K0471 -> 1.02 GB file on MEGA
MHS2_US_AU_P1242 -> 1.01 GB file on MEGA
MHS2_US_AU_P2037 -> 1.02 GB file on MEGA
Software update instruction -> 720.9 KB file on MEGA
After using the activator unit will accept modified meta.
What you need to do is take the meta from 1242, remove any SupportedTrains or BlockedTrains and then replace MetafileChecksum with skipMetaChecksum.

For for example with the meta from 1242:
Remove those two lines
BlockedTrains = "MHS2_EU_AU_P01*,MHS2_EU_AU_K01*"
MetafileChecksum = "cd15b1487917b24e0ca50e0716bfa3d6dd7d710d"

And add these two:
EnableUserDefinedSWDLMode = "true"
skipMetaChecksum = "true"

Then make sure all components are select, the bare minimum is - MCM,78K0R,AP_ZR_HIGH1,TNRREF. Nice to select SpeechRes,SpeechAppRes.

Keep in mind that if something goes wrong you might not be able to fix it yourself and might need to send it to me.

Thanks, I have looked there but I have a MSH2 head unit in my Audi and the maps are not listed for the US. Guess I’m still waiting for @congo solution to the issue

or without need of actual maps, using AppConnect (activated after using congo activator) then with Carplay or Android Auto,
works also great with the Google Maps
Thanks for helping the screen shot. Also it'll take a while even with good speeds. Best idea is to use a download manager.

Thank you for the activator. I have an Audi Q5 with MHS2_ER_AU_P2035. The activator (2.3) worked for me, and I can use the new maps too. I want to use android auto and I bought a ODBeleven, but I see now I have only charge only interface. Can I use android auto any way in my car?
Yes you can use Android Auto, but you have to update the USB interface. There are many tutorials in the web. You can use Google to find them.

just install the CONGO ACTIVATOR, then if hardware missing see here the video how to do

you need the cable(because of data connection/connector) today your usb are only charging! and
you need this 1x usb interface because inside they have the chip for data (license) inside!
HI EVERYONE! First of all I want to thank @congo for the magnificent work with the activator for Delphi, I have managed to unlock the car navigator in my audi a3 8v with version MHS2_ER_AU_P2035 working with maps 22 those of 22/23 I have not succeeded yet but I am very happy, I just want to ask a couple of questions that I have, first is how I can add POIs to MYAUDI special destinations to add fixed speed cameras (here in Spain it is totally legal) and second if there are some more functions that I can activate, to What use are the software applications and because now the OPS system does not appear on the screen when I approach an obstacle with Drive gear, in Reverse it always appears together with the reversing camera, thank you very much and best regards.

Hi Everyone, thank you very much Congo for your instructions on how to activate the maps in the MMI. However, in my case it is that I only have a "Charge only" USB port in my AUDI A4 2017 car. I wanted to ask if even with such a configuration I will be able to install the maps according to your instructions. I don't understand what exactly the sentence in your instructions means "If you have the Charge only one then Smartphone interface will not work. You need to change the AMI interface and install the required wiring."

Does this mean that the maps will work, but some others will not?

Thanks for the reply.
what firmware you have actual? check it via using red menu

sentence in your instructions means "If you have the Charge only one then Smartphone interface will not work.
You need to change the AMI interface and install the required wiring." see also here

Thats for having the Android Auto or Carplay working after use of congo activator, so its for this wish!

In your case maps, that will work!
Hi Congo, and thank you for your immense work!
I wanted to ask everyone do you know anything about mhs2 mmi base to activate Google earth?

Hey guys, im new here. I was trying this, and, I think I did a stupid mistake that might cost me my unit (MHS2) :cry:

I was using the activator, but radio sometimes has this bug coming from media. And since its just quicker to make a reset, other the restart the car... I used the typical key combination to restart the MMI, but I forgot that I had the SD already inside the unit with the activator. Well, it's on a boot loop. The MMI doesn't go past the initial boot, takes some seconds and boots again. I know I did it wrong, its a stupid mistake, I might be fucked, I'm accepting my destiny. Is there a way to solve this without going to Audi selling my soul and a leg?
