Sorry to hear bro. I haven't had either problem with mine. Yeah if I had to do it all over again I'd prolly not get the B&O and get the Drivers Assistance Package instead. I do like the look of the B&O though, so it was probably that combined with the high fidelity if the B&O that did it for me. So far I'm enjoying the B&O very much though. I blast the music as much as I can. Lol!
The F10 M5 is the Business Sports Sedan I always wanted. Until the next M5 comes out.
