MMI 3G 3G+ High Display Audi A4 8K, A5, A6 4F, Q7, Q5

The Multi Media Interface (MMI) system is an in-car user interface media system. MMI consists of a single integrated interface, which controls a variety of devices and functions of the car. 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.

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
• Media sources (CD changer, Audi Music Interface, aux audio port, TV tuner, two external AV sources)
• Telephone and 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, interior lighting, Audi Side Assist settings etc.)
• Rear view camera and parking sensors
• Driver information (e.g. fuel economy statistics (often encompassed by "trip computer" functions), battery level, oil level, tire-pressure monitoring, etc.)
• User manual (full on-board car user manual, displayed on screen)
