Multi Media Interface
Concept
MMI consists of a single interface, which controls a variety of devices and functions of the car, thus minimizing the vast array of buttons and dials normally found on a dashboard. The system consists of the MMI terminal and the MMI display screen.
Like in the mentioned iDrive the central element of the MMI terminal is the control dial. This dial can be rotated, to navigate up and down through menus, and pressed to activate a selected highlighted function. Four or eight function buttons surround the control dial (dependent on MMI specification installed in the car), which can be used to call up a corresponding on-screen menu. The MMI screen is available as a 5-inch monochrome black & red or 7-inch 16:9 full colour display, depending on the variation of MMI fitted in the car. MMI uses Media Oriented Systems Transport (MOST) technology to interconnect the various systems. Harman Becker manufactures the system, utilizing QNX Neutrino's Real Time Operating System (RTOS) software.
Variations
a right-hand drive 2005 Audi A6 (C6), showing the Multi Media Interface (MMI) controls
a left-hand drive 2007 Audi S6 (C6), showing the MMI controls, and the display screen in the dashboard
On the A6 and S6, MMI comes in a choice of 3 systems, MMI Basic, MMI Basic Plus and MMI . The features of the 3 varieties are as follows:
MMI basic
5-inch monochrome display (red and black)
optional CD-ROM based satellite navigation (with single country street-level maps)
radio tuner (with RDS Traffic Programme (TP))
single CD player
MMI basic plus - all features of MMI basic, plus:
DSP 10-speaker sound system
ability to store (TIM) RDS Traffic Announcement messages (TA)
MMI - the features of MMI basic plus, and the addition of:
7-inch 16:9 full-colour display
6 CD Changer
optional DVD-ROM based satellite navigation (with Europe-wide/United States-wide street-level maps, and TMC)
optional TV Tuner
For the current A8 and S8, and the forthcoming Q5 (although this may change when the car is widely available with a finalised full specification and options list), the MMI only comes as a complete "one size fits all" package.
On the current Q7, it is available in two specifications, the standard MMI (with 8 speakers, monochrome display, and radio/CD player, and 4 function keys), and the optional MMI High (7" hi-res colour monitor, double tuner extended radio, DSP sound system, and separate CD changer - but NO navigation, which is an extra option).
The latest version, due to appear in 2010 on the new A8, can recognize handwriting inputs for the phone and navigation system.
Functions
MMI operates a large number of in car entertainment components, car electronics, and other functions. The list below indicates the scope of systems controllable by MMI. However, depending on the actual car model, along with which version was specified (MMI basic, MMI High, etc), only some, and not all functions will be applicable or available.
Satellite Navigation, including traffic management (TMC)
Radio tuner
CD Changer
TV Tuner
Telephone & Directory
heating, ventilation, air conditioning / Climate Control, and seat heating
Car Setup (e.g. central locking and convenience function (coming home/leaving home, power sunroof and windows) options, global audio settings, suspension settings etc.)
Driver Information (e.g. fuel economy statistics (often encompassed by "trip computer" functions), battery level, tire-pressure monitoring, etc.)
User Manual (full on-board car user manual, displayed on screen)
Cars
Audi models featuring MMI are:
A4 (B8) 2008 onwards
A5
A6 (C6) 2005 onwards
S6 (C6) 2006 onwards
A8 (D3) from the 2005 facelift onwards
S8 (D3) 2006 onwards
Q5
Q7
Criticisms
While intuitive and user-friendly, MMI can be difficult to operate when driving. A sequence of menus may need to be accessed in order to change a particular setting, such as radio station, rather than having a dedicated button designated to such a function. This can make changing a setting both time-consuming and arguably hazardous under certain circumstances, where the driver is distracted from the road. It must be said, however, that this concern can also apply to other dashboard interfaces and even conventional dashboards.
Other information
Lists of miscellaneous information should be avoided. Please relocate any relevant information into appropriate sections or articles. (January 2009)
The MMI systems firmware can be updated, either by a dealer, or by a more recent release of navigation software. Bug-fixes, and enhancements can be added in this process, and on first installing a new navigation DVD, the firmware version is updated and system altered.
MMI featuring DVD based navigation has a DVD disc drive located in the boot/trunk. This is used exclusively for navigation and contains the navigation software DVD.
Pseudo-MMI
Certain Audi cars have a "pseudo" type of MMI. These are the A3, A4 (B6 and B7), the TT and the R8 - when fitted with the RNS-E DVD based "Audi Navigation Plus" system. Whilst appearing to be a similar layout, and operating in a similar manner, these two systems are very different, are unable to share mapping discs or software, and are not able to control non-ICE functions (such as Climate, convenience or suspension settings).
Competing Technologies
Other car manufacturers use similar technologies in their car, including BMW with its iDrive system and Mercedes-Benz with its COMAND system; Lexus uses a mouse-based Remote Touch system; Ford uses a product called Sync.
