As the title suggests, I've recently bought an A3 (out of Audi warranty) with the B&O system. I love it, however from time to time the stereo seems to forget the bass & treble sttings. I spke to Audi and they want £60 just to plug a laptop in to it, any firmware update would obviously cost more. Does anyone know if this is something I can do myself please? @DJAlix do you know please?!
