Inside, the RDX is all Acura, decked out in leather trim and brushed metal. Too much metal, in fact: on a sunny day, the sun glares off the dashboard trim pieces and slightly impedes visibility while washing out the navigation system’s screen. Otherwise, there are few surprises inside the cabin, where sturdy seats hold occupants nicely, and controls are well marked and easy to reach. The navigation system is excellent, with large, sharp graphics and an intuitive approach to the main control knob. With such a class-leading system, it makes us wonder what it would take to make navigation standard in all models – an extra $2,000?
