E70 USB retrofit

Hi guys,

I have a few question before I start the retrofitting. I have an X5 - 2007 (E70), equiped with:
- CCC Pro
- HiFi audio
- MULF low (bluettoh w/o USB) -SA 644, SA 609
- the software of the whole car is from 06-2010
I've get a used MULF high (with USB port) and I want to replace it with MULF Low.
1. do I need to provide extra cables for MULF high (for plug X14133)?
2. Is the USB hub mandatory?

As I see in retrofit instruction:

Cars with SA 640 or SA 644 only

3. This part pertains USB hub so could be skipped:

Route branches A5 and A6 in the luggage compartment
and connect to the same colour in plug X14133 (54-pin)
using miniature connector F as follows:
- Branch A5, BR cable, to wire from PIN 36
- Branch A6, RT/GE cable, to wire from PIN 17
Connect the fibre-optic cable plug (1) to High charger/
hands-free electronic control unit C.

4. The old cap fits into socket (with small modifications)

Replace the original cover cap of plug X14133 with
cover cap J.

5. Is this means I have to reconfigure socket for MULF high:

Connect branches A9 and A12 as follows to
plug X14133:
- Branch A9, VI cable, to PIN 4
- Branch A10, WS/RT cable, to PIN 5
- Branch A11, WS/GN cable, to PIN 22
- Branch A12, shield, to PIN 23
?

7. Programming
a. add SA6FL to FA
b. refresh the car (NCS)
c. code CCC
correct?


best regards

M.
