Hi Alex,actual software you use?
With the A6 4G / HN+R, the "BoseG3_C7" folder (and all subordinates within it) must be specifically deselected at BOSE before the update is started.
If this is then set to "N", it also works with the sound after the UPD, without re-parameterization. ;-)
Thanks for replying
Well, new update !
The component protection is gone, it looks like the head unit recognise all the other units (still the original units)
For the story:
I've proceed to all the update of the firmware up to the last on (provided on the post) and allways carefully uncheck the Bose update for each update.
Everything was working fine.
After that, I instaled the GPS Map and try to crack it (unsuccessfully).
Only after that my cd/dvd/etc... stoped working. but all the Bose setting are still available...
I will try to look if their is an "uncomplete or unsuccessfull update" pending.
