The deep-set, electroluminescent speedometer and tachometer are lovely, illuminated in a modern-looking amber shade. A trip computer/vehicle information display is nestled in the speedometer, and has a real-time fuel economy function. However, the display is too small to show more than 16 characters at the same time. Therefore, only one function (the trip odometer, standard odometer, fuel economy, the gear indicator for the manual mode for the XR's six-speed automatic, and so on) can be viewed at any given time.
Interior trim is mixed in quality but pleasingly designed, with padded materials covering the curvaceous dash top and door panels, but less impressive hard plastic most everywhere else. There are other materials as well, including generous swaths of silvery metallic or wood-grained plastic trim, made more attractive by chrome details in many well-placed locations. We would like to say that these materials are up to snuff compared with Toyota, Honda and even Hyundai, but in truth, they're not quite there.

All controls, buttons and knobs feel upscale in their operation. Controls for the standard, six-speaker, AM/FM/CD/MP3/XM stereo, as well as the optional, 240-watt eight-speaker sound system include presets that are not band-specific; in other words, AM, FM and XM stations can exist in the same bank of buttons; no need to change bands. This makes a big difference when jumping around to your favorite stations in everyday use. For example, it takes just one press of a button to jump from your favorite AM talk radio station to your favorite FM music station or to your favorite XM news station. The premium audio system has separate controls for rear-seat passengers and a pair of wireless headphones. Auxiliary input jacks are provided for iPods and other MP3 players.
A GPS navigation system is not available for the Aura, but the latest version of OnStar (version 7.0) includes turn-by-turn directions. This navigational feature delivers the guidance benefits of a conventional, map-based navigation system with voice commands. But instead of having to input destination information on a touch screen, which can be dangerous while in motion, the driver presses the OnStar button, and an OnStar adviser comes online to assist in finding the destination. After talking to you, the OnStar adviser uploads the Next Page
