Hello everyone.
First of all, thanks for the @congo activator!

I have a 2017 Audi A3 8V with MMI version MHS2_ER_AU_P0470 0191 and was able to activate it successfully.

It had the Charge Only port, I bought the "5Q0 035 726 E" module with the appropriate wiring, and proceeded with the installation to activate CarPlay/Android Auto.

I coded with ODB11, Media 5F, (apple_dio = on, google_GAL = on, and byte 19 with usb_ipod).
Restarted MMI, plugged in my iPhone with iOS 18.5, and nothing happened...
Plugged in my Android phone, and Android Auto started!

Any clue why? I've used CarPlay on my iPhone in other cars, and it worked...

Best Regards

MHS2 navigation and firmware updates are currently at the 2023/2024 version. Make sure you’re using the latest maps and firmware for the best performance and compatibility.
 
Update:
current version 2.5

If you used version older than 2.3 its recommended to install this one.
From version 2.2 and above there is option to remove the patched files in case the unit does not want to work ok or goes in reboot loop.
To do that take empty SD and create one empty file on it called "remove", put that SD in the unit and restart the unit. Once booted it should remove the patch and on next boot will start with stock software. This is only in case something with the flash goes wrong as there are some
events that can case data corruption and this might affect the SWaP process.

Whats new in version 2.5 - Seems that on older software versions there are conditions that might prevent the unit from booting after the first restart. This version is attempt to eliminate that risk. No need to reinstall, this "bug" can be triggered only during install not after that.

Whats new in version 2.4[/B] - added check to help avoid potential failure where unit might not start after the first reboot. Although there was only one case and it’s not verified that latest version of the activator was used, I have decided to make minor change to help avoid such cases. No need to reinstall, this "bug" can be triggered only during install not after that.

Whats new in version 2.3 - moved the patched files from persistence to ffs partition. Although i never had such case there is a possibility that data corruption might happen in persistence partition. If you are running 2.2 you are kind of safe as in case something goes wrong you an always remove it. Process is documented in "Emergency removal" paragraph of the manual.

Whats new in version 2.2 - patch support for almost all firmware versions. Emergency removal option.
Thanks for the clear breakdown! I’ll update my MHS2 to P2035/MU235 firmware, apply the Congo patch, then load the 2023/2024 navigation maps. Appreciate the detailed steps and cautionary tips.
 
Hi Congo,
I have an MHS2_ER_AU_P2035 (MU:0235) unit with Wi-Fi limited to diagnostic mode. I successfully used your activator to enable Android Auto via USB, but I’m wondering if there’s any way to enable wireless Android Auto, even though the Wi-Fi module is restricted.
Have you ever seen a case where someone managed to unlock wireless AA on an MHS2 unit with diagnostic-only Wi-Fi? Is there any patch, workaround, or hardware mod that could make this possible?
Thanks for your amazing work and for sharing the activator. Best regards from Spain.
 
Hi Congo,
I have an MHS2_ER_AU_P2035 (MU:0235) unit. I have successfully added the activator. However, i'm based in Australia, and the map link i think is only for EU.
Does anyone here have the map download for any recent year for rest of the world which includes Aus/NZ?
Cheers

Does version 2.5 work on my Audi Q5 (MHS2_ER_AU_P1242), or should i install a new firmware update? I think the latest is MHS2_ER_AU_P2035 please help me out on this?
 
My friend recently bought Audi A4 2016 with this firmware version: MHS2_EU_AU_P0114 MU Software: 0102 is there any way he can add serbian or croatian language to the system?

Thanks in advance.
