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.
