E70 Information and Communication Technology
Introduction
Information and Communication Technology (IKT)
IKT comprises systems that inform or entertain the driver and other occupants.
Depending on equipment configuration, the IKT also serves the purpose of making avail-
able servicing-relevant data and sending messages in the case of emergency.
This Product Information provides an overview of the IKT topics. The components avail-
able at the time of the market launch are described with the help of the vehicle outline
diagram and the bus overview.
With the E70, a fiber optics-based bus is also used for data transmission in information
and communication applications IKT in the BMW X5.
The MOST (Media Oriented System Transport) is already known from the following
BMW vehicles:
" BMW 7 Series (E65, E66)
" BMW 6 Series (E63, E64)
" BMW 5 Series (E60, E61)
" BMW 3 Series (E90, E91, E92)
Navigation Systems
Map navigation (Professional navigation system) based on the Car Communication
Computer (CCC) is provided in the E70. The functions correspond with the areas already
known in the E60, E61, E63, E64, E90, E91 and E92.
Via the voice input, the CCC supports the entry of whole words for a country, town and
street. It is still also possible to spell the destination.
For the market launch of the E70 in the USA, the (RTTI) traffic warning system (Real
Time Traffic Information) is provided. The service is controlled by the "Traffic information
for navigation"option and is currently included in the range of functions of the
"Professional navigation system" option.
RTTI is transferred in the form of a data stream from particular FM stations. The data is
received from the CCC FM tuner, evaluated and made available for the navigation sys-
tem. In the navigation map, traffic issues are indicated by symbols. The traffic issues are
also available in a list. The list entries are then sorted by the current distance between
the vehicle and the traffic issue. If the traffic issue is on the current route, there is a voice
output.

E70 Information and Communication Technology
Voice Activation Systems
The High and Basic voice activation systems already familiar in the E60, E61, E63, E64,
E90, E91 and E92 are available. The High voice activation system is used in the CCC.
The Basic voice activation system allows operation of the telephone functions and is
used in the Telematics Control Unit (TCU).
Telephone Systems
The following telephone systems will be available:
" "Complete mobile phone station" option.
" "Carphone station"option.
"Telephone station" option comprises:
" Wiring harness to connect the Telematics Control Unit TCU, base plate, Bluetooth
antenna, SOS antenna, SOS speaker, microphone and emergency call button with
emergency call indicator lamp.
" Roof aerial with telephone aerial.

Note: All services named here are available without restriction for all equip-
ment specifications.
With the start of series production of the E70, the following new services are also
planned:
" Remote Door Unlock
Unlocking of the vehicle, triggered on behalf of the customer by the ATX service
provider.

The legend above applies for the two preceding input/output diagrams. The first one
shows the 'Professional' radio option, the second shows the 'Professional' with navigation
system.
Note: In the US version, CHAMP is fitted as the Professional radio and in the
European version, the M-ASK.
The difference between the two items of equipment lies in the activation of the GPS and
wheel speed signals. With the 'Professional' radio, both signals are sent to the Telematics
Control Unit TCU. With the navigation system, both signals are sent to the Car
Communication Computer CCC.
Communication between the mobile phone and the Telematics Control Unit takes place
via the Bluetooth interface.

Note: The legends apply for the two previous system circuit diagrams.
Thanks to the improved overview, the telephone systems with the stereo systems are
shown. The HiFi system is standard equipment in the US version. For more information
about these systems, see the "E70 audio systems" Product Information.
Depending on the equipment, the TCU is supplied with power via terminal 30g or termi-
nal 30g_f. A power supply via terminal 30g_f is necessary for provision of the BMW
ASSIST services:
" Remote Door Unlock Opening the vehicle doors for servicing
" Stolen Vehicle Recovery
The implementation of the Remote Door Unlock service is carried out via the (MOST)
WUP signal. The signal is used to wake up the vehicle. The (TCU) reacts to a call from the
provider, performed in the customer order. The (TCU) sends a signal via the (MOST)
WUP line to the Car Access System (CAS3). The (CAS3) then wakes up the vehicle.
The CHAMP receives the terminal 58g (lighting) signal via fixed wiring. The CCC receives
this signal via the K-CAN.
The eject button on the base board does not receive a signal from terminal 58g. The but-
ton is not illuminated.
