E60 Communication Systems
M-ASK Functions
The M-ASK undertakes the most important and central functions as well as control tasks
in the communication network. It is responsible for the control and communication of the
individual systems among each other. These tasks comprise the following main functions:
• MOST-CAN gateway
• LVDS driver
• MOST functions
• Radio function
• Audio master function
• Audio output stages
MOST-CAN Gateway
The M-ASK forms a gateway (interface) between the MOST bus and the K-CAN. The
gateway connects the various bus systems of the vehicle network. The bus systems
operate with different transmission rates and data formats. The information must be converted in the gateway in order to be able to use it in the various systems.
LVDS Driver
The LVDS driver (low voltage differential signal) receives the digital RGB signals from the
graphic processor. The LVDS driver converts the RGB signals into LVDS signals and
sends them via the LVDS cable to the central information display thus providing digital
image signals on the display.
MOST Functions
System Master
The system master function that was still part of the control display on the E65/66 is now
integrated in the M-ASK.
Power Master
In the E65/66 the power master function is in the control display and is now integrated in
the M-ASK. The power master performs the wake-up, initialization, power-down
functions.
The power master wakes the bus and is responsible for ensuring correct initialization of
the network. The network master is also responsible for initiating the power-down. Each
power-down is requested at this master and initialized by it.
6
E60 Communication Systems
Network Master
The M-ASK is the network master for the MOST bus. The network master undertakes all
control and monitoring tasks of the MOST bus. It performs following functions:
• Configuration Control - The network master detects the exact system configuration each time that the network is started and compares it to a stored target
configuration.
• Fault Code Memory - The network master contains the central fault code memory
of the MOST network. In addition to deviations from the specified configuration, all
faults that occur during operation of the network are stored in this fault code
memory.
Car Communication Computer
The car communication computer CCC is the central control unit of the High equipment.
The CCC comprises the functions of the M-ASK, plus some additional functions. Voice
control of the systems and the Professional navigation system with map presentation are
additionally possible in connection with the CCC. The CCC also contains the driver for
the rear passenger compartment display.
The CCC (to be introduced at a later date) will perform all the functions of the M-ASK as
well as offering the High Navigation and additional programming possibilities.
Controller
The controller is the central control/operating element for all comfort and several car
functions. The operating principle is identical to that of the E65. The directions in which
the controller can be pushed has been reduced to four.
The controller comes in two versions, i.e. basic and High. The basic version is fitted with
a mechanical locating mechanism for the checkback signal while in the High version the
controller function is electrically generated for the check-back signal.

The CCC is combined with a voice input system, which can be used to execute most of
the functions by way of voice commands in the communications network.
Head-Up Display
A further innovation in the E60 is the head-up display. Here additional information is
beamed into the driver's field of vision. The driver can read this information without having
to take his/her eyes off the road ahead, this representing an effective safety feature.
Rear-Compartment Entertainment Center
A rear-compartment entertainment center will be provided at a later stage in
conjunction with the CCC. This entertainment center will allow the rear passengers to
watch a DVD film on a second display in the rear compartment while the car is moving.
Headset Interface

Audio Master Function
One of the main functions of the M-ASK is the audio master. The task of the audio master is to collect, process and output all audio signals in the vehicle.
A further task of the audio master is to generate and make available the audio signals
(with exception of the direction indicator noise) required by the various systems in the
vehicle. The special acoustic signals are required for warnings or as information for the
driver such as the PDC signal, jingles (gong).
In addition to the generated audio signals, the following audio signals are processed and
output or made available on the MOST bus:
• Radio
• CD changer
• Telephone
• Navigation message
• AUX-In
• SDARS (US only)
The M-ASK controls all sound and acoustic setting requirements of the customer. The
level of a signal is not changed abruptly but rather smoothly, e.g. by mixing, fading in and
fading out or intermittent attenuation of the signal in the sink for the purpose of achieving
high quality overall acoustics.
The M-ASK ensures clear cut acoustic changeover between the sources when a control
unit is requested to output an information or warning signal. The acoustic signals or
audio sources requested in the M-ASK are output in accordance with a defined priority
structure.
Connection Master
The task of the connection master is to make available the channels for the audio sources
and the acoustic signals.
The audio signals are distributed over speakers defined in a list.
Example 1: entertainment sources at all speakers
Example 2: hands-free telephone front left and right

E60 Communication Systems
Audio Output Stage
The multi-audio system controller M-ASK features 4 audio output stages each with a
25W output rating. The output stages are designed as bridgetype output stages. An
electric fan feeds cooling air to the output stages and processors to ensure they do not
cause the M-ASK to heat up. The electric fan is temperature-controlled and is regulated
in three stages.
Audio Systems
Two audio systems are available:
• HiFi audio system
• Top HiFi audio system
The further developed central bass system have realized a distinct improvement in the
bass range compared to the E39. The Top HiFi audio systems offers additional features
such as 7-band graphic equalizer and surround sound.

E60 Communication Systems
Multi-Audio System Controller
The M-ASK controls the stereo audio system. It contains the tuner for radio reception.
Furthermore, the output stages for the audio outputs are integrated in the M-ASK. The
M-ASK features four output stages each with an output power of 25 W.
Central Information Display
The CID serves the purpose of displaying and controlling the radio and audio functions.
Controller
The menus in the CID are selected and activated via the controller.
Mid-Range Speakers
The front and rear mid-range speakers are identical. In the HiFi audio systems, the speakers have a load rating of 25 W. The midrange speaker is equipped with a paper
diaphragm. The effective frequency range is from 100 Hz to 15000 Hz.
The front mid-range speakers are located in the doors. The rear midrange speakers are
mounted under the rear window shelf.
Central Woofers
High sound pressures can be achieved with the aid of the central woofers. A sufficiently
large space for the resonance volume is made available by connecting the central bass
housing to the sill area of the vehicle. The high sound pressures of the central woofers
create a distortion-free bass in the low frequency range.
The two central woofers are located in the vehicle floor under the driver's and passenger's seats. The output of the central woofers is directed upward under the seats.
Modified central woofers are used in connection with the HiFi audio system. The central
woofers have a diameter of 200 mm and a load bearing capacity of 40 W. The transmitted frequency is between 30 Hz and 500 Hz.
HiFi Amplifier
The HiFi amplifier is designed as an analogue two-channel amplifier with an output
power of 2x40 W. The HiFi amplifier is connected via two channels to the M-ASK. The
input signals are amplified via integrated band filters and bridge-type output stages to
2x40 W and output to the central woofers.
The control takes place via the M-ASK. Due to the distribution of the output stages in the
M-ASK and in the HiFi amplifier, the output stages must be switched on/off synchronously. The time required to switch on the output stages must not exceed 25 ms to ensure no
crackling or clicking noise is heard.
The HiFi amplifier does not feature diagnostic capabilities.
The HiFi amplifier is installed on the rear left in the luggage compartment.

E60 Communication Systems
Tweeters (High-Range Speakers)
The HiFi audio system features additional tweeters (high-range speakers) at the front and
rear. In connection with the HiFi audio system, the speakers are designed with a load rating of 25 W. The tweeters are equipped with spherical caps made of silk. The effective
frequency range is from 5000 Hz to 20000 Hz.
The tweeters are connected in parallel with the supply line of the front mid-range speakers. The frequency range is determined by means of capacitors in the supply line. The
tweeters feature an enclosed self-contained design, i.e. the speakers and resonance volume form one unit.
The front tweeters are located in the mirror triangles while the rear tweeters are mounted
under the rear window shelf.

Top HiFi
Top HiFi Components
The Top HiFi audio system differs from the HiFi audio system by higher grade speakers
and the addition of following components:
• Top HiFi amplifier
• Front mid-range speaker mounted centrally in instrument panel
• Mid-range speakers in rear left and right doors
Higher grade speakers are used in the Top HiFi audio system. The midrange speakers are
equipped with aluminum diaphragms, the tweeters with aluminum spherical caps. The
speakers were adapted corresponding to the higher output power of the Top HiFi
amplifier.
Top HiFi Amplifier
The Top HiFi amplifier is designed as an analogue 7-channel amplifier (LOGIC7). It features 7 bridge-type output stages with an output power rating of 7x40 W at 2 and a
bandwidth of 200 Hz - 20 kHz. In addition, two bridge-type output stages rated 2x70 W
at 4 and a bandwidth of 20 Hz - 200 Hz are available for the central woofers.
This amplifier is connected via the MOST bus to the M-ASK. All audio signals are transmitted from the M-ASK via the MOST bus. The Top HiFi amplifier is equipped with the
LOGIC7 function.
LOGIC 7
LOGIC7 is a registered trademark of Lexicon, Inc., a company of the Harman International
Group. It was especially developed for applications in motor vehicles.
LOGIC7 is a sound system that creates a 7-channel surround sound from 2-channel
audio sources (radio, CD, CC). The incoming stereo signals are decoded in the digital
sound processor (DSP), distributed over 7 channels and remixed. The entire transmission
width is used on each channel, thus creating perfect surround sound that gives the listener the impression of being in the middle of the space.
Mid-Range Speakers
The load rating of the mid-range speakers was increased to 40 W for the Top HiFi audio
system. The mid-range speakers are equipped with aluminum diaphragms. aluminum
diaphragms are particularly lightweight and feature a higher rigidity. These properties
result in improved inherent dynamics and a clearer sound over the entire frequency range.
The effective frequency range is from 100 Hz to 10000 Hz. The Top HiFi audio system
was extended by three mid-range speakers. A mid-range speaker was positioned in the
center of the instrument panel in order to realize the surround sound function in the vehicle. Two further mid-range speakers were integrated in the rear doors.
17
E60 Communication Systems
Tweeters (High-Range Speakers)
The tweeters (high-range speakers) have also been adapted. The load rating was
increased to 40 W. The tweeters are equipped with aluminum spherical caps. They feature sealed design. The effective frequency range is from 5000 Hz to 20000 Hz.
Central Woofers
Compared to the HiFi audio system, further modified central woofers are used in the Top
HiFi audio system. The central woofers have a diameter of 200 mm and a load bearing
capacity of 70 W. The transmitted frequency is between 30 Hz and 500 Hz.
Audio CD Changer
The audio CD changer in the E60 is a new development. The following details have
changed:
• The housing dimensions are smaller and more lightweight
• The magazine is newly designed
• The CD changer has an optical bus link
The magazine is newly designed and now features a transparent cover making it possible
to see what compartment is loaded with a CD. The new design now also differentiates
distinctly from the DVD magazine.
As before, the CD changer is designed as a 6-compartment changer with magazine. The
housing dimensions have been distinctly reduced so that less space is required, making it
possible to fit he CD changer in the glove compartment.
The CD changer is located in the units carrier behind the glove compartment. The glove
compartment must be opened in order to change the magazine.
A new feature is the optical link to the MOST bus. The CD changer sends the digital
audio signals via the MOST bus to the multi-audio system controller.
In the Top HiFi audio system, the digital audio signals are sent directly to the Top HiFi
amplifier. All controls and operating signals are also sent via the MOST bus.

Telephone Systems
In the country-specific version US, the option comprises the complete telephone preparation including telematics. A part of the telephone preparation is installed ex-factory, the
remainder is retrofitted in the USA. The complete preparation consists of the following
components:
• Telematic control unit TCU (standard)
• Telephone antenna (standard)
• SOS antenna (standard)
• GPS antenna (standard)
• Bluetooth antenna (standard)
• Hands-free microphones (standard)
• Eject box (retrofitted in USA)
• Motorola mobile phone Phoenix V60 (retrofitted in USA)
• Compensator (retrofitted in USA)
• Emergency call included for one year, then optional customer pay.
Telematic Control Unit
The TCU is always installed in the country-specific version US even if no telephone was
ordered. The telematic functions emergency call and breakdown call are standard features. The scope of functions differs from the EU version by following features:
• The TCU is always installed to
facilitate the emergency call
even if no telephone is fitted
• Dual band 800 MHz and 1900
MHz
• Combined transceiver module
NAD (network access device)
for the analogue AMPS standard (American Mobile Phone
Standard) and the digital
CDMA standard (Code
Division Multiplex Algorithm)
• Eject box with charger for
Motorola Phoenix V60
• Telematics Unit (E/B) Call
• GPS Receiver

Voltage Supply and Power Management
The power management module in the TCU monitors and controls the voltage supply of
the telephone system. The telephone system is switched off in the event of undervoltage/overvoltage in the system network.
MOST Bus Interface
The TCU is connected via the MOST bus interface to the MOST bus and therefore to the
bus systems of the vehicle. Control data (e.g. telephone book entries) and audio signals
for voice output (voice of call partner) are transmitted via the MOST interface. The TCU is
woken up by the MOST bus.
Bluetooth Antenna
The Bluetooth antenna operates in the ISM band (industrial science medical band) on a
frequency of 2.45 GHz. It is located under the rear window shelf. It is connected directly
to the TCU.
Note: To ensure unrestricted reception, care should be taken to ensure that no
objects are placed on the rear window shelf as they could considerably influence the reception capability of the Bluetooth antenna. (Not available at SOP)
Multifunctional Steering Wheel
The multifunction steering wheel has a send/receive button for accepting and ending a
call. The TCU switches to hands-free mode if the call is accepted by pressing the receive
button.
Multi-Audio System Controller M-ASK
The multi-audio system controller is responsible for the control of the MOST bus and
channel allocation. It also controls the audio output at the speakers.
Controller
The controller is used to operate the telephone functions. Various menus can be selected
and the functions executed with the aid of the controller.

Design
The design of the TCU in the US version is identical to that of the EU version (Everest
platform). The difference is in a different transceiver module (NAD) that is adapted to the
specific requirements. The TCU features a modular design and is equipped corresponding to the country-specific version and requirements.
Operating Principle
In the US version, the telematic control unit features a combined transceiver module NAD
(network access device). The NAD operates in accordance with the AMPS/CDMA standard with the frequencies 800/1900 MHz.
The TCU features an antenna selector switch for the AMPS/CDMA antenna. The TCU
operates in the digital CDMA network. If a sufficient network supply cannot be ensured,
the TCU switches over to the AMPS network. The widespread AMPS network is used
especially in rural areas.
If the option Professional navigation system is not installed, the TCU will be fitted with an
internal GPS receiver. The GPS receiver is connected to the GPS antenna that is integrated in the roof antenna. In the US version, the telephone/telematics functions are available
in three stages:
• Basic
• Business
• Professional
Eject Box
The eject box is an additional component that must be retrofitted in the USA. The eject
box serves the purpose of accepting the Motorola Phoenix V60 mobile phone and is
located in a compartment in the center console.
The charger for the mobile phone is integrated in the eject box. The antenna connection
for the AMPS antenna is also located directly in the eject box. Data transfer from the
mobile phone to the TCU takes place by means of a multi-core cable (P2K, point to connect).
Motorola Mobile Phone Phoenix V60
The Motorola Phoenix V60 mobile phone is the standard telephone in the US version.
The mobile phone is also a component part of the retrofit.
All functions are available only when the mobile phone functions are provided. The telephone book is integrated in the mobile phone. SMSs can only be sent with the mobile
phone.

E60 Communication Systems
Compensator
The compensator is connected in the antenna line between the roof antenna and the
mobile phone. The task of the compensator is to compensate for losses on the antenna
line and to ensure the full transmit power of the mobile phone is available at the roof
antenna. The compensator is not an amplifier that boosts the transmit power output.
SOS Antenna
The SOS antenna is fitted as standard under the rear window shelf. It ensures an emergency call can be sent even after a crash and failure of the roof antenna.
GPS Antenna
The GPS antenna is integrated in the roof antenna. It receives the signals from the satellites of the global positioning system and sends these signals to the GPS receiver.
