BMW 7 Series: System Components

Components and Installation Locations

The following control units act as the interface between the mobile phone and the vehicle:

• ULF-SBX-High Interface box (Only for USB/Audio Interface)
• Telematics Control Unit (TCU)

The preconditions under which TCU or TCU and interface box together are installed are listed below:

TCU INSTALLATION REFERENCE CHART

NOTE: Although both the ULF-SBX-H and the TCU may be fitted in a vehicle at the same time, the TCU always provides the telephone functions. The ULF-SBX High is only installed to provide the "USB audio interface".

ULF-SBX-H Interface Box

The ULF-SBX High interface box has been used in BMW vehicles since the introduction of E93.

The (SBX High) interface box is capable of performing the following tasks:

• USB connection for USB/audio interface
• Bluetooth interface with hands-free mode and phone book
• Basic voice input and activation system through the telephone

Interface box and interface box 'High' support various techniques for downloading phone book entries from Bluetooth-enabled mobile phones. One of these techniques is Phonebook Access Profile (PBAP). The number of compatible mobile phones increases with the support of several downloading techniques. In addition, it is possible to download all the phone numbers attached to a name entry.

Although both the ULF-SBX-H and the TCU may be fitted in a vehicle at the same time, the TCU always provides the telephone functions. In this case the telephone functions are not available in the ULF-SBX High and the module is only installed to provide the "USB audio interface" option.

Telematics Control Unit (TCU)

The Telematics Control Unit used on the F01/F02 evolved from the E70 TCU.

The TCU always incorporates a GPS receiver and a GPS connection. In the F01/F02, however, this connection is not used because the GPS signals are processed by the CIC.
