Bluetooth Update Keeps On Failing

[loftygit]

Hi,

I have a 2009 Ford Focus Zetec with the Audio pack which includes the Blaupunkt sat Nav and bluetooth.

All was working well until the infamous iOS 5 update.

I have downloaded the Ford bluetooth update and extracted the files to various USB sticks of different sizes and with different formats (FAT, FAT32 etc)

Each time I first turn on the radio, insert the USB stick in the socket in the central armrest/console, then turn the ignition to position II.

I get the message that BVC is updating then I get "BVC device update failed.Please try again"

Using the Set+Navigation trick I have determined that my firmware version is 0828-090731, but I don't know how to find out the bluetooth version.

Has anyone else seen this message and managed to get it working? If so How??

Any other ideas will be gratefully received.

Thanks.
