Modular Infotainment System (MIB*)
The Modular Infotainment System is another milestone achieved by the Volkswagen Group and in future will replace the information and
entertainments systems used up to now.
The control unit architecture allows the hardware to be easily and economically updated so that it always incorporates the latest advances.
An important component is the fast graphics processor made by market-leader Nvidia, with whom Audi enjoys a very successful business
relationship. The latest Nvidia processors will continue to be used in Audi cars in the future.
The new platform means that it will be possible to use the same central processing units (electronic information systems control unit 1
J794) across the entire Group. So in future it will be possible to run brand-specific variants on four standardised hardware platforms. For
the purposes of dierentiation, features such as the user interfaces and controls will be individually adapted for each brand. Customers will
thus be able to identify distinctive dierences between the systems. And the system used in an Audi will always be recognisable as a
genuine Audi MMI.
The Modular Infotainment System (MIB) was first used on the Audi A3 ’13.
In all Audi oers three MIB configuration levels:
• Entry MIB
• Standard MIB
• High-spec MIB
One Group brand is responsible for each of those configuration levels. Audi is responsible for developing the High-spec MIB, Volkswagen for
the Standard MIB and Skoda for the Entry MIB.

Introduction
Why does Audi use the Modular Infotainment System?
Due to the high pace of development in the field of multimedia
applications, keeping up to date with the latest advances is a
growing challenge for car makers. One example is that many
mobile phone manufacturers update their top-of-the-range
products every year while also extending the software functional-
ity. Car owners, in turn, want to be able to connect the latest
mobile phones to the in-car entertainment and communication
systems.
To keep up with the speed at which requirements are changing,
the development cycles for information and entertainment
equipment in the automotive industry have to be made shorter as
well.
To make that achievable, the electronic information systems
control unit 1 J794 has been designed as a modular unit. That
means that in future new designs will only need to be produced
for some control units while other hardware can be retained.
Thus the components that are not subject to such rapid develop-
ment, such as radio tuners or audio amplifiers, can remain as they
are.
Put simply, that means that only the computer (MMX board) in
the electronic information systems control unit 1 is upgraded. The
MMX (Multi Media Extension) board itself is equipped with an
Nvidia dual-core processor on the Audi A3 '13. Specifically, it is
the Tegra T20 unit which has a clock speed of 1.2 GHz.
If the MMX board is upgraded in the future, the changes required
can be compared with replacing the motherboard and graphics
card in a home PC to make it "faster".
The software for the MIB is also modular in design so that in the
future both "old" and "new" software will be used together on a
new control unit. The "old" software might then be the CAN data
protocol, while applications such as the Bluetooth profiles are
likely to frequently require the development of "new" software.

Note
If the electronic information systems control unit 1 J794 is replaced by an Audi dealer, it is replaced with an identical control
unit oering the same features.

Standard MIB navigation system version
If the radio-version MMI is set up for the navigation function, it
also has the following features:
• Second SD card reader
• Navigation system hardware
If the navigation function is activated on the radio-version MMI at
the factory, the navigation map data is also available in the car on
an SD card.
The navigation system data is currently supplied by the company
Navteq. For the European version, an 8-GB SDHC* card is currently
used.
The navigation system has a two-dimensional birds-eye view map
display.On the Setup menu it is referred to as the 3D map.There is
the possibility, depending on sales market, of displaying the
currently applicable maximum speed limits or the guideline
maximum speeds for the country concerned.

The navigation system uses a real ecological route calculation
algorithm and also oers the option of choosing between three
alternative routes. In addition, you can create a route with an
intermediate destination. If the driver takes a break, the route last
used is automatically resumed.
With the Standard MIB, the navigation system now oers the
option of entering a destination using the voice control function
as well as by manually entering an address. When doing so, the
user is assisted by predefined MMI prompts.
The PR numbers below indicate whether the Standard MIB is one
that is navigation-ready or with the navigation system pre-acti-
vated:

Navigation system activation
With the navigation-ready version, all the components required
fore the navigation function are already fitted on the vehicle. An
Audi dealer can then activate the navigation function on the
electronic information systems control unit 1 J794 with the aid of
the vehicle diagnostic tester.
After activation of the navigation function, the map data to be
used must also be activated. The necessary activation documents
for doing so are obtainable from the Audi Genuine Accessories
range.
To be able to use the navigation system, two components are
therefore required:
• An activation document for the navigation function
• Up-to-date map data (on SD card) together with activation
document allowing licensed use of the navigation map

High-spec MIB
The High-spec MIB is the current high-end version of the Modular
Infotainment System. The electronic information systems control
unit 1 J794 for the High-spec MIB always has a MOST bus connec-
tion. If no additional equipment connected via MOST bus is fitted,
the MOST bus connection is unused.
The High-spec MIB represents a consistent step forward from the
3rd Generation plus MMI and features a new 3D screen views and
SSD* solid state drive.
The electronic information systems control unit 1, J794, for the
High-spec MIB incorporates an Nvidia Tegra processor. As a multi-
core processor, it generates ultra high-resolution graphics as well
as oering faster rendering of current audio and video formats.
The Tegra chip requires substantially less energy than previous
multimedia processors and so fits perfectly with the Audi e-
ciency philosophy.
The Tegra chip can display entire cityscapes in three-dimensional
views – the driver sees the street that he/she is driving along in
photo-realistic quality.
The High-spec MIB is also the only version of the MIB that can play
video files directly.

Navigation system with High-spec MIB
The High-spec MIB features a navigation system with 3D map
display. It displays the silhouettes of many city centres as a
three-dimensional view. Many places of interest are also shown in
3D.
The navigation map data for the High-spec MIB is stored on the
SSD solid state drive. The 2012 map information for Europe, for
example, occupies approx. 23 GB of storage space. The current
map supplier for the High-spec MIB is Navteq.
The map data also includes predictive route data. This is sent by
the electronic information systems control unit 1 J794 via the
MOST bus to the data bus diagnostic interface J533. The J533
distributes the data via the various bus systems to the control
units that use the predictive route data.
The navigation system has a voice control facility featuring whole-
word entry. Depending on the country of sale, the navigation
system may also oer whole-sentence destination entry (one-shot
entry).
On the High-spec MIB, ten destinations can be entered for each
route. In other words, nine intermediate destinations and the
final destination. In all, twenty route plans can be created.

Radio tuner
The analogue radio receiver unit for the Modular Infotainment System is always integrated in the electronic information systems control
unit 1 J794. Depending on the equipment options fitted, the J794 may also include a DAB radio tuner.
The radio tuners support most of the RDS* services generally available today. Which particular RDS services are actually available in each
case depends on the station being received at the time in question.
The basic designs of the radio tuners for the Standard and High-spec MIB versions are explained below.
Analogue tuner reception concept
Standard MIB
The analogue radio receiver (tuner) for the Standard MIB has a two separate receivers in total.
Tuner 1 is an AM/FM tuner (see schematic diagrams on pages 16 and 17).
AM reception is provided exclusively by Tuner 1.
Tuner 2 is an additional FM tuner.
If FM reception is poor, the selected station is received simultane-
ously by Tuner 1 and Tuner 2. The two signals are then merged to
form a combined signal.
If the signal received by one of the tuners is good enough to ensure
interference-free reception and playback through the speakers is
possible, the other tuner is used for the station search function.
The best aerial-tuner path is always used for audio output (role
swapping).
Because a station search is carried out at regular intervals, the
main screen of the FM radio menu is constantly updated with the
FM radio stations currently receivable. The station list is thus kept
up to date and unavailable stations removed from the list.
Furthermore, the AM station list is also updated in FM mode if the
reception conditions allow – in which case Tuner 2 provides the FM
audio signal and Tuner 1 performs the AM station search.
If a navigation system is fitted, a third FM tuner (Tuner 3) is fitted
for receiving TMC* data. That tuner continues to be used for
monitoring trac bulletins if the audio tuner is not tuned to a TP
station. It is also used for the station search function if the recep-
tion conditions require the use of aerial diversity.
The separate station memory can be used to create a personalised
station list. It can store up to 50 stations from any reception area
and lists them in the user-defined order.
The radio supports the Radiotext and Radiotext Plus data services.
This enables programme-related information to be displayed if
broadcast by the station concerned (e.g. artist, title, current
programme).

High-spec MIB
The analogue radio receiver for the High-spec MIB has a three
separate receivers (tuners) in total. That means that both the
station search and the aerial diversity function take place simulta-
neously.
During FM reception, the selected station is permanently simulta-
neously received by Tuners 1a and 1b. The two signals are then
merged to form a combined signal. As a result, the best possible
reception is obtained.
Tuner 2 functions as a separate tuner for permanent AM/FM
station searching and for receiving TMC data and monitoring voice
trac reports. It is not used for audio reception of the radio
station currently selected. Because the station search function is
constantly active, the main screen of the FM radio menu always
shows all FM radio stations currently receivable. The station list is
thus kept permanently up to date and unavailable stations
removed from the list.
AM reception is provided by Tuner 1a.
Tuner 2 is an additional AM tuner which constantly updates the
AM station list in the background.
The separate station memory can be used to create a personalised
station list. It can store up to 50 stations from any reception area
and lists them in the user-defined order.

DAB tuner reception concept
Standard MIB
On the Standard MIB, the DAB tuner is a single tuner.
That means that automatic station list updating as on the ana-
logue tuner is not possible.
The DAB tuner is designed for receiving stations broadcasting
according to the following standards:
• DAB*
• DAB+*
• DMB* Audio
If reception of the DAB station is lost while the vehicle is moving
but it can still be received on FM, the radio switches over auto-
matically to the same station on FM.
This "station tracking" function can be activated or deactivated on
the Radio Setup menu. The "Station tracking" option activates/
deactivates automatic switching not only from DAB to FM but
also from DAB to DAB.
The DAB tuner supports the following data services:
• Radiotext (Dynamic Label)
• Radiotext Plus (Dynamic Label Plus)
• Trac Announcement
• Slide Show
Display during DAB reception
618_048
The Slide Show feature allows studio images, photos of artists or
album covers, for example, to be displayed if broadcast by the
station concerned.
The DAB tuner supports the frequencies in Band III (174-230
MHz) and in the L-Band range of 1452-1492 MHz. As the L-Band is
only available in local regions, it is deactivated on the "Settings"
menu by default.
DAB Settings menu
618_051
Note
The DAB tuner is coded for the country of sale as each country uses dierent frequency gaps between the individual channels.
If it is incorrectly coded, reception quality will suer.
20
Page 22
!
High-spec MIB
On the High-spec MIB, the DAB tuner is a twin tuner. That means
that the DAB tuner can constantly automatically update the list of
receivable stations. Consequently, manual updating is not neces-
sary. The stations on the station list can be sorted by "ensemble"
or in alphabetical order. The desired setting is entered on the DAB
menu under "Settings" and "Arrangement of stations".
The two tuners of the DAB receiver have equal priority and can
swap roles. If the selected station is being received by Tuner 1,
then Tuner 2 acts as the station search tuner.
The DAB tuner is designed for receiving stations broadcasting
according to the following standards:
• DAB
• DAB+
• DMB Audio
It supports the following data services:
• Radiotext (Dynamic Label)
• Radiotext Plus (Dynamic Label Plus)
• Trac Announcement
• DAB Announcement
• EPG (Electronic Programme Guide)
• Slide Show
EPG provides the facility for showing information about the
current and next programme on various stations, if the stations
concerned support the function.
If the DAB twin tuner automatically switches to a dierent
channel, Tuner 2 becomes the receiving tuner and Tuner 1 the
station search tuner. That enables continuous reception of the
selected station while on the move.
If reception of the DAB station is lost while the vehicle is moving
but it can still be received on FM, the radio switches over auto-
matically to the same station on FM. This "station tracking"
function can be activated or deactivated on the Radio Setup menu.
The "Station tracking" option activates/deactivates automatic
switching from DAB to FM.

Telephone options
The Modular Infotainment System oers three dierent ways of
using a phone in the car. They are:
• Bluetooth interface
• Universal mobile phone pre-wiring (Audi Phone Box)
• Bluetooth car phone online (Audi connect inc. car phone)
HFP A2DP
Simultaneous connection of two devices to MMI using Bluetooth
Bluetooth interface
Using the Bluetooth interface, a mobile phone can be associated
with the MMI by means of the Hands-Free Profile (HFP). With this
connection method, the mobile phone's address book is also
imported using the Phonebook Access Profile (PbAP*). Using the
voice control facility, the driver can then make a phone call
without taking his/her hands o the wheel.
The Bluetooth interface also supports Bluetooth audio streaming.
This requires connection of a Bluetooth-enabled device to the MMI
via the A2DP Bluetooth profile.
Note
The functions of the telephone option "9ZX" are also supported by options "9ZE" and 9ZK".
618_069
The Bluetooth-enabled device can also be controlled via the
AVRCP* Bluetooth profile. The AVRCP specification supported by
the MIB is 1.3.
If a mobile phone is connected using HFP, a second device can be
simultaneously connected using A2DP.
The PR number for the Bluetooth interface is "9ZX".

Universal mobile phone pre-wiring (Audi Phone Box)
The universal mobile phone pre-wiring option (UHV*) provides the
facility for linking a mobile phone to the car's external aerial and
charging the phone in addition to the Bluetooth interface func-
tions.
The Modular Infotainment System on the Audi A3 '13 sees the
introduction of the Audi Phone Box as the universal mobile phone
pre-wiring option (UHV). It enables mobile phones to be con-
nected to the car's external aerial via a link aerial without the need
for a specific adaptor. In the Audi Phone Box there is a 5V USB
socket for charging the mobile phone and, depending on equip-
ment level, the AMI interface as well.
To ensure good reception by the mobile phone, the mobile phone
signal is conditioned by the mobile phone aerial amplifier R86
(compensator). It is fitted in the signal lead between the link
aerial and the roof aerial. On the Audi A3 '13, for example, it is
located behind the luggage compartment trim on the right-hand
side.
The PR number for the universal mobile phone pre-wiring is "9ZE"
(the internal designation for "9ZE" is "Convenience telephony").

Bluetooth car phone online (Audi connect inc. car phone)
The option previously called "Bluetooth car phone online" has
changed to "Audi connect inc. car phone" as of the introduction of
the Audi A3 '13. For the sake of simplicity, it is simply referred to
as "car phone" in the remainder of this self-study programme.
If the Modular Infotainment System is fitted with the optional
"car phone", the electronic information systems control unit 1
J794 is equipped with a telephone module and a SIM card reader.
The "car phone" option also incorporates all the Bluetooth inter-
face functions. For example, a mobile phone can be connected by
means of the Hands-Free Profile (HFP*). In that case, the tel-
ephone module in the electronic information systems control unit
1, J794, is not used.
The telephone module fitted in the J794 is designed for GSM* and
UMTS* networks. There are two possible ways of activating the
telephone module:
• With a SIM card in the SIM card reader
• With the aid of a mobile phone associated using the SAP* (SIM
Access Profile)
The mobile network standard that the "car phone" is currently
using to connect is shown at the bottom right of the MMI screen.
For the GSM network it shows 2G and for the UMTS network it
shows 3G. If a data connection is also active, a two-headed arrow
also appears.

Audi connect (market dependent)
Audi connect is a collective title for applications and develop-
ments that make it possible to use the world of multimedia in the
vehicle and to connect with the outside world.
Audi connect also includes Audi Online services that were first
introduced on the Audi A8 '10.
Audi connect is available if the vehicle is equipped with Audi
Navigation plus and Bluetooth car phone online. Audi connect
services and applications can vary from market to market.
With the High-spec MIB, new services have been added to the
Audi connect services previously available.
The previous services and functions include, for example:
• Audi trac information online
• Google Earth
• WiFi* hotspot
The new services include:
• Facebook
• Twitter
• Flight Information
Some services, such as "Flight Information" for example, are
already activated when the vehicle is delivered and so can be used
straightaway. Other service, such as "Facebook" for example,
cannot be used until activated by the customer on the "myAudi"
website. To do so, the customer has to register online with
"myAudi". Customers can then configure their vehicle there. If the
configured vehicle meets the requirements for Audi connect, the
services available for that vehicle can be activated.
Audi connect also includes smartphone applications such as "Audi
music stream", for example.

Address book
With the Modular Infotainment System there is always an address
book available on the MMI if a telephone option or navigation
system is fitted. The address book entries are used for telephon-
ing or navigating.
The address book function distinguishes between:
• the mobile phone address book; this is imported directly from
the mobile phone
• the personal address book; this is entered directly on the MMI
and is assigned to a specific user profile
• the public address book; this is entered directly on the MMI
and can be used by all users
A mobile phone address book entry cannot be edited from the
MMI. If necessary, this must be done directly on the mobile
phone.
With the MIB, a total of 500 entries per user profile can be stored
on the MMI. In addition, up to 2,000 address book entries from
an associated mobile phone can be managed. Consequently a user
has a maximum of 2,500 address book entries available.
The public address book can also hold up to 500 entries.

618_078
The MIB provides the facility for creating up to four user profiles.
If another mobile phone is associated when there are already four
user profiles stored, one of the following options can be chosen:
• "Replace contacts": i.e. delete one device
• Restricted use of phone: use of the address book on the MMI is
limited (thus no personal local address book entries can be
created)
With restricted use, no personal entries can be created. The
general entries can still be used.

User profile
The user profile stores address book entries for a specific user. A
user profile is automatically created when
• a mobile phone is associated with the MMI via Bluetooth or
• a SIM card is inserted in the SIM card reader in the J794.
In all, four user profiles can be created alongside one another. The
data that is stored for a user profile is only shown on the MMI
when there is an active connection to the device concerned. That is
the case when, for example, the mobile phone concerned is
reconnected via Bluetooth.
If the vehicle has the Audi connect including car phone option
(9ZK), a mobile phone can be associated via Phonebook Access
Profile (PbAP) at the same time as having a SIM card in the J794.
A dierent user profile is then created and a dierent address
book used for the associated mobile phone. This is the case even
with a multi-SIM* card.

MMI display J685
Display unit for front information display and
control panel control unit
On the Modular Infotainment System, an LVDS* signal is used for
video transmission from the electronic information systems
control unit 1, J794, to the MMI display, J685.
With the Entry plus and Standard MIB, the video output resolu-
tion is 400 x 240 pixels, and on the High-spec MIB 800 x 480
pixels.
The electronic information systems control unit 1, J794, is con-
nected to the MMI display, J685, via a sub-bus system (private
CAN bus). This is a CAN bus with a data transmission rate of 500
kbit/s. The electronic information systems control unit 1, J794,
uses it to control and monitor system statuses on the MMI display
(on or o, temperature, error status, etc.), for example.

Video transmissions to J794
Video signals from up to four dierent sources for can be viewed
on the MMI display.
• TV tuner R78 (High-spec MIB only)
• DVD changer R161 (High-spec MIB only)
• A terminal device (e.g. iPod) connected to the Audi music
interface (AMI)
• Reversing camera control unit J772
The images from the various sources are transmitted to the
electronic information systems control unit 1 J794 via dierent
routes.
TV tuner R78 and DVD changer R161
The TV tuner R78 and the DVD changer R161 send the video signal
to the electronic information systems control unit 1 J794 via the
MOST bus.
Reversing camera system control unit J772
The images from the reversing camera system control unit J772
are sent to the J794 as finished images via a dedicated FBAS lead.
Terminal device on Audi music interface (AMI)
With the AMI, a distinction is made between two possible video
sources. They transmit the video signal by two dierent routes:
1. Video sources that provide finished images as an FBAS* signal.
Example: an image transferred from an iPod using the iPod
adaptor plus (red kink preventer) to the J794 via the FBAS
connection on the AMI connector.
2. Video sources that provide a video file. Example: a video file
on a USB stick is transferred to the J794 using the USB adaptor
connected to the USB socket on the AMI. The J794 then
converts the file into a video.

Control panel
(multimedia system control panel E380)
There are three dierent versions of the multimedia system
control panel fitted on the Audi A3 '13 with the Modular Infotain-
ment System. To allow even more intuitive operation, the number
of buttons on the control units has been optimised compared to
the previous systems. There are now two new rocker buttons
which can be used to choose between two menus in each case.
The volume control also has a right/left rocker action. It can be
used to skip backwards or forwards to the previous/next track on
the Music menu, for example.
The control panels are connected to electronic information
systems control unit 1, J794, via a private CAN bus
Two versions are fitted for the Entry plus MIB and the Standard
MIB. Technically, they are identical and dier only in terms of the
menu options available with the left rocker button. The third
version features the MMI touch in addition.
On the basic version, the left rocker button can be used to activate
the following menus:
• Tone
• Car
The next version is used if a Standard MIB (MMI Radio) with a
hands-free, telephone or navigation function is fitted. The follow-
ing menus can be activated with the left rocker button:
• Phone
• Navigation
The third version with the MMI touch is fitted in conjunction with
the High-spec MIB (MMI Navigation plus). In this case too, the left
rocker button is used to choose between Telephone and Naviga-
tion. In this case, however, the rotary push-button is slightly
larger than on the other versions.
Integrated in the rotary push-button is the touch-sensitive input
zone. This can be used to control the following functions:
618_060

Network systems
The electronic information systems control unit 1 J794 is con-
nected to the data bus diagnostic interface J533 via the informa-
tion/entertainment CAN on all versions of the MIB. The informa-
tion/entertainment CAN is a high-speed bus with a data transfer
rate of 500 kbit/s.
The MMI display J685 and the control panel E380 are, for the first
time, connected to the electronic information systems control
unit 1 J794 via a private CAN bus. This is also a high-speed bus
with a data rate of 500kbit/s.
If a vehicle is also fitted with an additional information/entertain-
ment control unit (e.g. the digital sound package control unit
J525), the system is also equipped with a MOST bus. Consequently
it is possible for the first time for an Audi vehicle to be fitted with
both the information/entertainment CAN and the MOST bus.
Due to the combination of the information/entertainment CAN
and the MOST bus, a break on the MOST bus does not result in
complete failure of the MMI. Thus all functions which are carried
out directly on the J794 remain available. However, audio signal
output via an external amplifier would not be possible.

Optical data bus system MOST150
History
The Audi A8 '03 saw the introduction of the first optical data bus
system, the MOST bus. To be precise, the MOST25. The data bus
system was named after a group known as the "Media Oriented
Systems Transport (MOST) Cooperation". This group is made up of
various automobile manufacturers, their components suppliers
and software companies, who joined forces to create a standard-
ised high-speed data transfer system.
MOST150
With the arrival of the Modular Infotainment System, the
MOST150 is being used on an Audi for the first time.
This developmental stage in MOST technology is six times faster
than the MOST25 bus.The development process necessitated
various modifications to MOST components. The transmitter and
receiver units had to be adapted, for example. Other components
such as the optical connectors, the fibre-optic cables or the
electrical connectors for the control units are identical to those for
the MOST25.
The term "Media Oriented Systems Transport" refers to a network
designed for transmission of media-based data. This means that,
unlike in the CAN data bus, address-oriented messages are sent to
a specific recipient.
This technology is used in Audi vehicles to transfer data within the
infotainment system.The data transfer rate on the MOST25 bus is
approx.25Mbit/s.
With the advent of the MOST150, the video signal from the TV
tuner R78 or the DVD changer R161 is transmitted directly via the
optical data bus for the first time. A separate FBAS connection on
the J794 as with the MOST25 is no longer fitted.
System and diagnostics manager
With the Modular Infotainment System, a maximum of five
control units are connected to the MOST bus:
• Electronic information systems control unit 1, J794
• Digital sound package control unit J525
• TV tuner R78
• DVD changer R161
• Instrument panel control unit J285
With the MIB, the electronic information systems control unit 1,
J794, performs the function of the system manager for the MOST
bus as well as being the diagnostics manager. That was previously
the job of the data bus diagnostic interface J533.
39
Page 41
Diagnosis
The diagnosis address code for the electronic information systems
control unit 1, J794 is the same on all MIB versions. It is:
"5F – Electronic Information Systems"
Ring break diagnostics
The procedure for ring break diagnosis is the same as with the
previous MOST bus system. However, with the MIB, the testing
program for ring break diagnosis has to be invoked on the vehicle
diagnostic tester using the address code 5F.
With the Modular Infotainment System the electronic information
systems control unit 1 J794 is also the diagnostics manager for
ring break diagnosis.
Although the ring break diagnosis sequence has remained the
same, a dierent tool has to be used for an optical fault on the
MOST150 – the optical substitute control unit VAS 6778. This is
because of the dierent transmitter and receiver units.
