E90 Communication
Information and Communication Technology refers to various systems in the vehicle that
that inform or entertain the driver and passengers.
Depending on the equipment configuration (BMW Assist), the IKT also serves the
purpose of making available servicing-relevant data and sending messages in the
case of emergency.
For the first time in this vehicle class, a fibre optics-based bus is used for data transmis-
sion in information and communication applications (IKT). This bus is the so-called
MOST (Media Orientated Systems Transport) bus as already used on the E65, E60 and
E63/4.
In this section you will be informed about the information and communication technolo-
gy available in the new BMW3 Series (E90). It deals with the following topics:
• Audio systems
• Navigation systems
• Telephone systems
• Voice recognition systems
Introduction to Information & Communication Technology

Audio Systems
Two audio sources are offered on the E90. Both are on the MOST bus and have CD
playing capabilities.
The base version utilizes a single cd drive and a dual LCD line readout and is referred to
as the RAD2 (‘Professional’ radio). This audio system can be ordered as a HiFi system
with 180 Watt capability or upgraded to Top-HiFi Logic7 with 420 Watts of power.
The second audio source is the familiar Car Communication Computer (CCC or
Navigation system, Professional). Because the CCC does not have an LCD readout,
it utilized the CID as a visual monitor. A vehicle equipped with CCC will always come
with the Top-HiFi Logic7 system with 420 Watts of power as standard.
The following new features have been introduced:
• New 'Professional' radio with MOST capabilities (RAD2 and CCC)
• Additional audio input for external devices
• Playback of MP3 files (RAD2 Directly / CCC with CD Changer)

‘Professional’ Radio (Rad2)
The 'Professional' radio is a new radio for the MOST system network.
The radio combines the following features:
• Player for CD/MP3/WMA files • Built in single radio tuner
• Most bus gateway to the K-CAN • Liquid crystal display
• Board computer readout • Personal profile management
The MP3 directory structure is the same as that of a PC. Up to 8 directory levels can be
represented. A maximum of 255 directories and a total of 999 music tracks per CD can
be managed.

Navigation System, Professional
The 'Professional' navigation system is based on the CCC (car communication comput-
er), the functions of which are already familiar from the E60 and E63/4.
The CCC combines the following control units in one housing:
• Navigation computer/GPS module; Map display and/or arrow view on CID (split
screen)
• RDS double tuner
• Audio system controller (ASK)
• MOST gateway
• Interface to control display (LVDS)
• DVD player
• CD player
When the navigation system is not in use, its DVD drive can be used to play audio CDs.
Together with the controller and CID, the CCC forms the iDrive system.

Amplifiers and Speakers
The audio systems in the E90 offers two choices:
• HiFi system -10 speakers w/separate amplifier
• Top-HiFi system (Logic7) - 13 speakers w/Logic7 amplifier
In addition to the higher achievable sound pressure, the audio systems are also distin-
guished by the improved system fidelity. For the customer, the additional features such as
the 7-band graphic equalizer and the spatial sound (Logic7) provide both visible as well
as audible added value.
The central basses are located under the front seats. They are coupled to the side sills,
thus enlarging the resonance volume necessary for bass reproduction.
The stereo, HiFi and Top-HiFi systems exhibit different performance features in terms of
symmetry of the sound field, sound pressure and fidelity of the frequency response.
Note: Even though the diameters of the speakers in the HiFi and Top-HiFi sys-
tems are the same, there are differences in the output of the speakers.
This is achieved by the use of different materials for the diaphragms,
coils, magnets etc.
To distinguish between them, the designations Medium and High are
used in the table above.

HiFi System
The analogue 6-channel 'HiFi' amplifier has the same technical specifications as the one
fitted in the E83. In the E90, however, it features settings specific to the E90 (diplexers,
equalizing).
The HiFi amplifier is located behind the rear left side panel trim in the luggage compart-
ment.
The audio signals are transmitted in analog form from the radios or navigation systems to
the HiFi amplifier. This amplifier amplifies the signals and transfers them to the speakers.
A total of 10 speakers are driven by 6 audio channels:
• A high-range and mid-range speaker in each front door
• A tweeter and a mid-range speaker on each side of the rear shelf
• A central bass speaker under each front seat
