Love them or hate them, Bose wants to be your car's media control center with the just-announced Bose Media System. What's particularly interesting about their system is the way it's controlled—via the device's two knobs (which have built-in proximity sensors). The two-knob set up lets you pick songs or cycle through the unit's functions, which include AM/FM radio, satellite radio, or CD playback. The unit also has a built-in 30GB hard drive, which holds your tunes as well as navigation data. You also get built-in Bluetooth and a USB 2.0 input for plugging in your MP3 player. No word yet on pricing, though it doesn't look like it'll come for cheap.
