Hi everyone I want to update my current mmi firmware to the lastest version.

I have heard that the newer update drastically improves the sounds quality of the b&o system which is my main reason of wanting to update.

I will be purchasing the file from "upgrademyaudi" but it does say additional steps need to be taken with vehicles which have the bang olufsen system and a fibre optic loop adaptor is required.

I am quite unsure how this comes in to play as I thought it's just a file that needs to go on a memory card and it's as simple as that I hope you guys can help me out.

My current firmware version is MHIQ2_ER_AUG222_P4212

I will be updating to the following firmware

mhi2q_er_aug22_p5092
