This review of the Audi MMI system was conducted in an. MMI systems in other Audi models will differ in specifications and interface.
As before, the controls at the heart of the MMI system consists of a push button dial flanked by four control buttons. To simplify matters there's a series of shortcuts to the radio, entertainment media, navigation, telephone, car and traffic information (not available in Australia) functions. On either side of the central set of controls is a volume knob grouped together with the audio switches, and a multi-purpose touch pad. These controls manipulate the large LCD screen that rises out of the centre of the dashboard.
Using the central push button dial is pretty self-explanatory, although we never did warm to rotating the dial counter-clockwise to move down a list. The four buttons flanking the dial correspond to the menu items, if any, that are listed in the respective corner of the screen — this also takes a bit of getting used to, as other computer interfaces don't require you to look at all four extremities of the display.
Depending on which screen you're in, the touch pad lights up with different controls. For instance, it can be used to scroll around the navigation map or as a data entry input. Most of the time, though, it serves as an easy way to access the six radio station presets. That said, it's far too easy to graze the pad and accidentally go from the current batch of beats to a long block of non-stop rock.
When entering nav destinations or searching through the phone book, you can scroll through a batch of letter or numbers to get where you're going. Alternatively, the touch pad jumps into handwriting recognition mode, with words entered letter by letter. Recognition speed is on the slow side, but the most obvious flaw (for most of us) is that in right-hand drive cars, writing is done with the left hand.
Two screens are better than one
A second smaller, but pleasingly high-res screen resides between the tacho and speedo. It's controlled by a scroll wheel and a few buttons on the left spoke of the steering wheel. In addition to the comprehensive trip computer, the driver has access via this screen to the active cruise control, telephone and entertainment systems, and can also view nav instructions and the infrared camera.
With the ability to switch between different types of media, as well as change tracks and albums, twiddling the left thumb became our preferred method of music selection. Whether we were stopped at the lights or spending another hour on the highway, it allowed us to perform simple tasks without taking our eyes too far off the road.

The voice recognition system proved to be another successful way of keeping our eyes on the road while interacting with the MMI. Simply press the talk button on the right steering wheel spoke and the system will helpfully display on the central LCD screen a list of relevant commands for the current MMI function. Mind you, in the interests of on-the-go safety this list would be better off in the instrument display.
Unlike on, users can issue orders for a screen that they're currently not on. So, for instance, if you're in the telephone section and you utter "cancel navigation", MMI won't shrug its shoulders at you.
Voice commands work fine without any training and the success rate with menu items was very high. It's also able to understand with a high degree of accuracy contact names from your phone book, although it struggles with the names of music files stored on the hard disk and requires you to spell out navigation destinations letter by letter, which can be tricky for places such as Wollongong, Woolloomooloo or Wollondilly.
