Hi Elio,

FLAC devs can't do anything about this.

You should talk to Audi. But I wouldn't hold my breath if I were you.
3G-Plus MMI is old and most probably only in maintenance mode.

Audi is using QNX as their "Unix-Line RTOS" OS, which is
proprietary nowdays and developing something for the Audi MMI
is impossible for 3rd parties.

Cheers,
Cristian.
