Its iDrive user interface consists of an LCD panel mounted in the dashboard and a controller knob mounted on the center console, and it controls a vast and disparate number of functions in BMWs.
In the center console is the very appealing touch-screen navigation and audio controller, which will synch up with your phone and play your music library wirelessly through the bright, fearsome Fender audio system.
Microsoft is expected to show off enhancements to its Kinect motion controller, which the company hopes will transform the Xbox from a gaming device into an entertainment center for the entire family.
The center stack is dominated by the 8-inch touch screen, above a gloss-black panel with the rotary controller for the Sony sound system (there's a smaller LCD between the gauges in the instrument cluster).
While the Xbox 360 requires a quick trip to the dashboard to edit things like resolution and audio output, the Echo is easily configured without a gaming controller, thanks to a user interface that has the same look and feel as the rest of Media Center.
