I got another black BT box from ebay, removed the CPU and traced the tracks as per the datasheet.
Pinouts of the connector are attached.
The only pins I'm not 100% on are the 2 x 3v3 pins, they seem to go through some diodes direct to the 3v3 supply. I cant see them going to anywhere else, so I'm fairly sure that they are just supply.
