Anyone fond of options will approve of the GS 450h's audio setup. That's because there are multiple ways to work with your favorite tunes, including steering wheel controls for volume, channel, and mode; traditional radio buttons for functions such as seek and scan at the bottom of the instrument panel with specific chrome-ringed dials for volume and tuning; and, finally, an Audio button that works with the center touch screen and adjusts sound, changes stations, and more. A multi-disc CD player is at the ready for more contemporary tunes, while a cassette player is waiting to belt out some classic ABBA or Toto.
