Yes def can be wrong. Maybe the document was released before the MY08 Cars. I'm not sure but it took me 5hrs to figure out.
I am not sure of what get transferred over the fiber optic loop but sound is one an this is the direct way how modules "talk" with each other. If the MULF is not connected on the loop correctly it will never talk to the car; even if it is receiving power via the wired harness. Also would explain why the tel options and such wouldn't pop in on the radio.

As a side note, you will loose the Aux connection in your center armrest when the MULF2 starts working correctly. Aux input is now handled over the MULF2. This maybe because of the 6FL VO option.

Let's figure how to get the module working in the car first though.
