Universal charger and hands-free system E60, E61, E63, E64, E81, E87, E90, E91, E92, E93: Introduction
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 only contained in the customer's mobile phone.
From this point in time on, the two control units can be fitted at the same time.
The interface box High (ULF-SBX-H) then serves solely option 6FL "USB audio interface". The telephone function is not available in the ULF-SBX-H. The TCU provides the telephone function.
Further information about how to sign a bluetooth mobile phone onto the ULF control unit can be found by following the link below.
The benefits of the universal charger and hands-free kit are:
- The driver is prohibited by law from making a phone call with the mobile phone in his hand while he is driving.
However, phone calls can conveniently be made using the hands-free system.
- The bluetooth connection is automatically established between vehicle and mobile phone.
- Speech processing, allowing telephone operation in hands-free mode:
- Select a phone number from the telephone directory
- Make a connection
- Accept a phone call
- If the vehicle is equipped with the Car Communication Computer (CCC): The telephone functions can only be operated in hands-free mode using option 620 "Voice recognition system". Other CCC functions can then be operated using voice commands.
- Transmit and receive via the vehicle's external aerial. The occupants receive less exposure to electromagnetic fields.
- Charging mobile phone battery
Option 644 is not included and must be retrofitted by the customer:
- Bluetooth mobile phone
- Snap-in adapter
All bluetooth mobile phones that are supported by BMW can be used with option 644. These mobile phones have been checked with regard to suitable software.
