The Bentley Azure T Interior is no different from the standard-issue Azure. New for 2009 is the custom Naim sound system, which integrates with phone and navigation. Naim engineered the system for the Azure convertible; its 11 speakers include two subwoofers tucked in the footwells of the rear passenger seats. They're enclosed in specially designed cases to keep the sound inside the car -- top up or down. The volume is also self-adjusting, depending on speed and top position.
