Universal charger and hands-free facility E60, E61, E63, E64, E87, E90: Introduction: Notes

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2005 BMW 645Ci, 2005 BMW 545i, 2005 BMW 530i, 2005 BMW 525i, and 2004 BMW 645Ci. However, it is still accessible from the selected car via links, so may be relevant.

The identifying feature of option 644 "Basic fittings for mobile phone with bluetooth interface" is the "universal charger and hands-free facility" (ULF).

The ULF serves to connect the bluetooth-compatible mobile phone to the vehicle's electrical system. The ULF control unit is connected to the MOST bus (Media-Oriented System Transport).

The ULF does not contain its own transmitter and receiver module for GSM communications (GSM: Global System for Mobile Communication). This function is contained purely within the customer's mobile phone.

For more information, refer to E60, E61, E63, E64, E87, E90: ULF SYSTEM OVERVIEW .

Information about bluetooth mobile phones approved by BMW is available from the BMW Parts Service. A compatibility matrix is available there.

The bluetooth connection is automatically established between vehicle and mobile phone.
