Can someone please help me with some wiring info?

You're welcome to ring me in Italy mate, then can go through it.

Think you need to backdate the software as per my email advises to get the software back to a usable state with the nav disc, did you wait for it to complete without removing the disc, it should advise when its updating & should restart when completed, can take 5-10 minutes in all, did you use nero to write the disc, not windows.

Cal, so where we at now?

Cool & you cant downgrade without changing setting with vagcom anyway.

You need to read comments on that sds thread about wiring, should advise you there easily where things go & you may need repair wires from audi for quadlock.

When at 0650 check rns works ok then write a cd/dvd with sds hack & just insert disc into rns & see if it says software update on screen, dont touch anything, just let it update by itself, dont turn of ignition or anything until update done & rns auto reboots by itself, then test rns & check software version shows 0660.

When you copy files to disc to write with, make sure you use nero not windows & also make sure windows is showing all files as in, go into Windows Explorer, then Tools, then Folder Options, this opens small window, goto the View tab, check that Show Hidden Files/Folders is ticked & Hide Extensions is not ticked, then click OK.

You should have 5 files on the disc when written & the Index.txt file should show:

SOFIDX:0660
NAVVER:V2200815
AUDVER:A2210141
