Hello all, I have kindly been given access to the CNSD-310FM EU 2012 update and have the CARDINFO.cif and VERINFO.DAT files which hopefully with a little help from pionara, will make the update function for us EU users?!
The full update is currently uploading so i will post a link to that once it becomes available. (21%)
The link for the full update is here

To do the update on an F930BT you just have to:
01) Download the rar from the link above above.
02) Extract it to a safe place.
03) Open the extracted folders and go into the Update folder
04) Replace the VERINFO.DAT with the one in pionara's second post on this thread.
05) Copy everything you extracted onto a clean 4GB+ SD Card
(make sure that the files and folders on the route of the SD card are:
FIRMWARE (folder)
Update (folder)
CARDINFO.cif (file))
06) Put it in your Car (with the engine running or on a charger etc)
07) The Pioneer should reboot and start the update.
08) Follow the on screen prompts
09) Once completed, it may ask you to update again, if so, select no.
10) Enter Bluetooth settings and update the bluetooth firmware. (This seemed to take longer than i expected but dont worry, it does eventually get there! 
The above files are not a hack to do the upgrade, they are the official Pioneer Update Files. The only hack is with the VERINFO.DAT which I believe all it does is bypass the passcode request when the update starts. There shouldnt really be any reason for this to fail.
As always, with anything like this, I would always advise you backup first!
Cheers, Radeonorama
