Evening all and Merry Christmas!

Does anyone know exactly what is required to retrofit a USB port to an LCI E60?

Is it as simple as fitting a MULF2 High and running a HSD cable to the USB port which I would fit in the centre console? I presume I would reroute my existing AUX input wiring to the new port too for the 3.5mm Jack.

Is the 54pin plug different from the TCU to the MULF2 high...? And would I run the new MULF parallel to the TCU or simply replace it?

Currently have the basic M-ASK(champ) with a retrofitted & simplified SA633 setup(like 644 but with out SOS/Assist)
