Acura is getting a better grip on its infotainment interface. Audio controls can be accessed through the screen via the center controller, voice commands, or the redundant controls on the steering wheel. Plus, for those who abhor combined navigation/audio systems, there's a full set of hard radio keys at the bottom of the center stack. They aren't ideally sized or located, but they exist. Of course, the result is the appearance of clutter – a door to hide them would be swell. Navigation is stupid simple to program, the mouse controller is firm and sturdy, zoom is simple to use, route cancellation is front-and-center, and the system offers a variety of extra features.
