BMW Universal BluetoothTM
Introduction
The BMW Universal BluetoothTM Hands-
Free System (ULF) utilizes BluetoothTM wire-
less technology to enable a wireless con-
nection to be established between a
BluetoothTM enabled mobile phone and the
ULF Control Module installed in the vehicle.
The combination of these components
results in a new generation of in-vehicle
phone system.
The ULF Control Module forms an interface
that allows a mobile phone with the embed-
ded BluetoothTM wireless technology feature
to be wirelessly integrated into the vehicle.
For the first time BMW is introducing a new generation hands-free telephone system kit
that provides the customer with the option of using various BluetoothTM enabled mobile
phones (a list of recommended phones is available from your BMW Center).
What is BluetoothTM?
The name BluetoothTM is derived from the Danish King Harald Bluetooth who lived in the
10th century. He was well known for his ability to unify his kingdom and today lends his
name to a wireless technology standard that can connect/unify various electronic devices
that are BluetoothTM enabled and located within a short range (approx. 10 m or 32.8 ft) of
each other.
BluetoothTM wireless technology is
a short-range radio frequency tech-
nology standard that allows several
devices to communicate with each
other simultaneously. The standard
indicates that up to seven simulta-
neous connections can be estab-
lished and maintained at one time,
as long as the connected devices
are within a range of 10 m (32.8 ft).
Note: The ULF system will
allow four phones to be paired
to the system at a time and only
allow one phone to be connect-
ed at a time.

Communication/Security
The system uses the license-free, global Industrial Scientific Medical band (ISM) at 2.45
GHz. This frequency range from 2.402 GHz to 2.480 GHz is subdivided into 79 channels
with a 1 MHz bandwidth.
Signals transmitted through the airways can be scrambled and unscrambled to enhance
communication security. With BluetoothTM technology, communication frequencies are
changed 1600 times per second to reduce the risk of interference or interception of the
transmitted signal. The relatively small operating range of approx. 10 m (32.8 ft) also
enhances the security of this technology, since tampering with the transmitted data is
only possible when inside the 10 m (32.8 ft) wireless "network".
To further enhance the security of this short-range wireless network the ULF system
requires a pairing procedure to be carried out for each device that will be introduced into
the network. As part of this procedure a required passkey must be entered once (during
the initial pairing procedure) to establish a secure connection between the phone and the
ULF Control Module.
Data and Voice
BluetoothTM was developed for the transmission of both voice as well as data. A band-
width of approx. 1 MB/s is available for this purpose.
BluetoothTM Enabled Phones
Ideally all phones that are BluetoothTM enabled should work with the ULF system, howev-
er not all phones utilize the same profiles and therefore may not be recognized by the
ULF System. A list of recommended BluetoothTM enabled phones is available from your
BMW Center.
Advantages of the ULF System
• Once a phone is paired to the system it will be able to automatically connect to the
BluetoothTM wireless network of the vehicle, the next time it is introduced into the
vehicle and the vehicle ignition is on.
• Up to four different BluetoothTM phones can be paired to the system at one time,
although only one phone can be wirelessly connected at any time.
• The phone does not need to be inserted into a phone specific cradle in order to be
integrated into the vehicle.
• The phone can remain in a briefcase, purse, glove box, etc.; as long as it is turned on
and located within the interior of the vehicle.
• The MFL buttons on the steering wheel can be utilized to place or receive a call, to
scroll the phone book and select a number or activate voice recognition in order to
dial a number via voice command.

• A voice recognition system is integrated into the ULF control module and can be
activated by depressing the send/receive button.
• The communications protocol of BluetoothTM wireless technology is standardized
irrespective of the manufacturer, this therefore allows various mobile telephones that
utilize BluetoothTM wireless technology and a recognized profile to be connected to
the ULF System.
System Overview
A ULF system consists of a control module, microphone, BluetoothTM antenna, a stand-
alone pairing (send/receive) button, or eject box with a coin tray insert.
ULF Control Module
The ULF module forms the interface between the BluetoothTM mobile phone and the
electronic system in the vehicle. The mobile phone with the embedded BluetoothTM
wireless technology is the transceiver, this requires that the phone be activated, paired
and present within the vehicle network in order to place or receive a call in the vehicle.

ULF System Overview

Oddment Tray
The oddment tray, which is connected to the
ULF control module via the vehicles wiring har-
ness, serves the purpose of:
Housing the send/receive or pairing
button, which must be depressed to activate
the pairing procedure between the phone and
the control module.
Pairing Button
A stand-alone send/receive or pairing
button is supplied for the 3 Series in order to
retain the cup holders. The button provides the
same function as the send/receive but-
ton on the steering wheel, plus is the button
that must be depressed to activate the pairing
procedure between the phone and the control
module.
BluetoothTM Antenna
The BluetoothTM antenna operates on a frequency of 2.45 GHZ and is installed in the
interior compartment of the vehicle. This antenna provides the wireless interface
between the BluetoothTM enabled phone and the ULF Control Module.
System Operation
Initial Operation
Prior to using the system for the first time, the BluetoothTM mobile phone that is to be
used must be paired with the ULF control module. This pairing procedure is necessary
in order to assign the digital code of the mobile phone to the ULF control module
installed in the vehicle. The pairing procedure is only required when a new phone is
introduced to the ULF system for the very first time or the list of paired devices is cleared
form the memory of the ULF module, it does not need to be performed every time the
phone is used with the system.
After pairing, the mobile phone is recognized automatically by the ULF control module
within 45 seconds after it is introduced into the vehicle and the ignition is turned on.

Note: Depending on the mobile phone manufacturer, particular care must be
taken prior to initial operation to ensure that no headset is coupled with the
mobile phone. Various devices may interpret the ULF control module as a
headset and request deactivation of the headset. Please refer to the operating
instructions of the mobile phone for detailed information.
Pairing Procedure
The pairing procedure that must be initiated through the phone will differ corresponding
to the different menu configurations of the various BluetoothTM mobile phones on the
market. The user's manual of the phone manufacturer should always be referenced for
specific steps on how to activate the BluetoothTM feature and to pair/link devices.

System Functions
The mobile phone must always be activated, paired and present within the BluetoothTM
network in order to place or receive a call through the vehicle.
Indicator Lamps
The indicator lamps show the following:
Active call (green light)
No mobile phone in range
(steady red light)
No network (flashing red light)
Adopting Telephone Book
Depending on the type of BluetoothTM mobile phone, the telephone book is either trans-
ferred automatically (ex. Nokia 6310, Sony Ericsson T68i) or manually (depending on
software version of phone) by the user to the ULF control module. The address book is
stored temporarily for the purpose of accessing/displaying stored phonebook information
using the steering wheel controls or telephone menu selections available on the display
screen or some radio displays.
If a manual transfer of the address book must be made, the ULF must be in setup mode
for manual transfer. The corresponding data can then be transferred. If phonebook data is
modified while the phone is wirelessly connected to the vehicle the changes will not be
displayed in the vehicle if the phonebook is scrolled via the steering wheel or display
screen, changes will only be transferred the next time the ignition is cycled.
Placing a Call
A call can be placed in several different ways:
1. Using the keypad or address book of the mobile phone and depressing the send
button on the phone.
Note: Some phones may ask if the call is to remain within the phone. Refer to
the users manual of the phone for specific instructions on disabling this fea-
ture.
2. Depressing the R/T button on the steering wheel, then scrolling (using the or 
buttons) through the address book of the phone that is linked to the ULF, until the
desired number is displayed on the radio or display screen and then depressing
the send/receive button on the steering wheel or center console to place
the call.
