Thanks for the reply
For reference for others I tried removing fuse m12 did nothing.
Disconnected the battery and left for an hour completely fixed missing Bluetooth and ability to pair phones.
Must be a software lockup. Amazed they don't make it easier to reset the hardware. It's there but hidden so only engineers can get to it.
Mine by the way works pretty well with an iPhone 4s.
No text messaging but can stream spotify through it reasonably well.
Only noticeable issue being a slight lag in skipping tracks.
