Has anyone found a way to get music files from a Windows Phone 8 device to appear on a f310bt headunit?

I've recently upgraded from an iPhone to a Windows phone 8 and have lost all functionality of the USB input.

 

Suggestions?

I have the same issue since today . Also Bluetooth not working for making phone calls. I can not even pair the two devices. I have a HTC 8S Phone.

Any ideas are welcome!
