Looking for firmware update for Toyota C-HR Hybrid Flame 2021

Hello,

I have a Toyota C-HR Hybrid Flame 2021 ZYX11L-AHXNBW 1798 cc 122 HP LHD. Here are the details of my model:
  • Model ID DCU: 17TDT1EU-DA31
  • Parts No. DCU: 86140-F4070
  • My audio system is currently on version 1075.​
See the pictures below for more information on my car, system and model:

I would like to upgrade my multimedia system to the newest version.

Does anyone know where I can get the firmware update for my car? I can't find it anywhere online.

I came across this thread from 2020 that has the same model ID as my audio system:
https://www.chrforums.uk/threads/orange-edition-and-co.3368/post-26893

The firmware attached from the 2020 thread is 17TDT1EU-DA31_0076.kwi, currently I have 1075.


P.S.: I am from Israel, not the UK. Toyota would charge me 200 GBP just for the firmware update.

bonjour pouvez-vous m’aider à installer la MAJ du logiciel je suis actuellement sur la version 17TDT1EU-DA31. Le carplay lag énormément quand je suis en appel téléphonique. J’ai mis sur une clef usb en FAT32 mais ça ne détecte pas la mise à jour. La clef usb elle est bien détecté.
Merci d’avance

Would you give a link for your blog too?
I think I know what the procedure is, but if you describe it there, especially with some screenshots and estimated time it will be a good piece of mind.
What I know is that I have to extract the file from the zip. Put it onto an empty usb drive, formatted in fat32. Get my car in Ready Mode. Disconnect any other usb devices. Plug in the usb drive, wait for a bit. A pop up should appear or I go into Settings and start the update. Then just wait patiently and don't turn off the car. Is this it?
