Thank you, Nissan designers, for the big ol' center dial marked Power. It's hard to miss, though I wish what looks like a rubber grip was just that and not hard plastic. Those simple little things can make a big difference. But, let's return to the positive, such as clearly-marked buttons for seek, tuning, audio adjustments, and presets, which are appreciated just as much as the auxiliary jack located just below the power button. Steering wheel-mounted controls are also well marked and include volume, tuning, mode, and Bluetooth functions. Our tester's sound quality and reception left something to be desired, despite coming from a 340-watt Rockford Fosgate system, part of the $750 Rockford Fosgate Audio Package.
