Old thread I know, but if anyone is still interested, here are a few answers for the record. The 9000 is not intended to play CDs while the car is in motion, however "soundproof" was correct in guessing that the BeoSound 2 delivers the audio input on the move. The 9000 unit travels very well in motion, and has cushioning for the unit and specifically the glass to counter motion caused in transit. Though it is primarily a showpiece, and despite seeming quite eccentric, it was a remarkably successful installation and the sound is of course exceptional. There are various other hidden functional aspects that make the system practicable, but the car has not been permanently altered to accomodate anything. The unit can also be plugged back into mains electricity indoors in situe. The idea was simply inspired by how well the look of vehicle and stereo seem to complement each other, and an enthusiam for both!
...so for the record, the Mercedes-Benz SLS AMG is not the first gull-wing to incorporate Bang&Olufsen equipment....!
Many thanks for the interest
