OK Frogman, thanks to your help I'm getting further.

After checking that FA still has 6NS in the edited file I go through Shawns instructions.
When I press "code" on the NBT ECU it goes through the update and NBT seems to reboot and I get a message saying its all completed.

Unfortunately when I try my phone I still don't see any bluetooth audio!!

So a couple of questions.
1/ When the update is running I get a box that opens and tracks the progress. I can't copy the contents so I could paste it here. Is it stored as a text file somewhere?
Update: Found it under Logs :-(
2/ When I "code" the NBT ECU do I select the top folder rather than the file above the CAFD?
3/ Are the changes immediate? Some of the other posts seem to say wait a while before changes take effect.

Thanks again.
