Aygo 2014-12 model, firmware update

[RST2612]

Hello,

I am a owner of a 2014-12 Aygo with the X nav system. Currently I am on version 0810- 0621. I have read that the most up-to date is 0850, can someone give me a link to this update, much apreciated!
Also, I want to update the satnav because I am on 2014 version, so there is a version of 2023, but I don t know where to get it.

If someone can show me and also with instructions, appreciate it.
Also, dont mind my English, it s not my native language.

Thank you.

Regards,

Retek
