Good evening guys, sorry I'm using the translator, I would like to ask a question to the experts, according to you on an A 3 8v you can do an update of the 5 F module in a previous version, I'll explain it better, there is no way of operating the voice button on my A 3 8 V that was not present at the origin, now it is mounted the internal software 040 0461 nn working for the voice command, I managed to know that the previous version was 039 0421 was fully functional, according you can install on the control unit software before the current one?
Thank you all
