Mmi 2g update - optic loop?

[Echo]

Hi everyone.

when updating the MMI 2G software/firmware, is it still a wise choice to use an optic loop on the DSP AMP to avoid component protection?

Or, is there a de-select option in the red menu before you hit the start button?

Here is my MMI version.........no laughing at the back!



I have genuine Audi dealer discs:

4E0 906 961 H - 1 CD.

4L0 998 961 - 3 CD's.

Are these all I need for the 5570 update from my 07.7.0?

I also have an optic loop if needed.

Also, as I don't have a phone in the car, I can skip CD 2 of the 3 set.......yes/no?

Thanks.
