Are you a BMW dealership?
If you are you should be familiar with the hardware.
Do you have BMW diagnostics?
If not you should get some or you will have no hope of working
on these cars.

Bimmergeeks.net cable and basic downloads set up on a PC gives
factory level diagnostics (Ista D ) and coding software.
There is a fuse diagram on the rear panel of the glove compartment.
see location in Entertainment PDF.
If these modules are replaced they must be programed for features and
to match the VIN number.

Bluetooth and USB comes from modules in the Trunk in BMW's of this era.

2006 TCU module provides bluetooth phone and bmw SOS
2007 ulf or mulf module added for usb drive. can have a tcu to
2008 Can have a TCU and Mulf module stacked and in the trunk for both

Tcu telephone control unit it is essentially a cell phone with the bluetooth and SOS
in it . SOS is similar to GM onstar but no longer supported because its 2g.
But the bluetooth phone connection for calls should still work.
