I love the fact that Bentley has installed a standard stereo with easy-to-use knobs in the Arnage. No mouse or menu navigation here. The stereo controls are distinctly separate from the navigation screen and located high in the center console for easy access. The navigation screen is manually opened with a discreet switch located next to the sunroof switch and navigated using a small plastic remote. The whole system looks to be an afterthought and didn't work so we couldn't test it.
