Yes, thank you Mr Simpson & Paul.
I couldn't reply earlier today as the forum was down (well for me anyway), and I couldn't see your posts, so I just went for it.
I decided to use the optical loop on the DSP amp to avoid the component protection, hopefully.........
Started with the 4E0 906 961 H disc.
This was the update list..........
What's IDC?
Also, the Nav wasn't included in the update?
Maybe it'll be included in the later discs. No, not there either!
Anyway, that finished and I then ran 1 & 3 of the 3 disc set: 4L0 998 961.
Left number 2 out with not having the phone.
Not sure what the 'S' means?
And this is what I ended up with............
The SW 'VERSION' isn't on the bottom right of the MMI 'car' screen anymore, it's in the 'car' settings now, don't know why.
Took about 1 1/2 hours, but I was so relieved
The radio and speakers seem ok, so looks like the optical loop worked then!
Did a VCDS scan and there were some fault codes, but mainly for the loop when I took it out the DSP and put it back again. Also, fault codes for no sound, well there wouldn't be would there, with no amp showing, so just cleared them, and final scan showed they'd been rectified.
I'm just concerned about the Nav though. Why didn't it update with the other stuff? Anyone got an answer for that one?
I had already bought a 2019 - 2020 map DVD:

I swapped it with the old 2004 DVD, but all I got was this........
So I put the old one back, which is working fine, though outdated.
Very pleased that the update to 5570 went well, but a bit miffed at the Nav bit.
Many thanks for your help.
