I did some research and despite Ford's claims about BT on their website, it's pretty much clear that if you don't have USB then BT streaming does not work.
I stumbled onto this thread where you can retrofit USB (BT module and USB cable) at a reasonable cost (approx $300) and make it all work. It just takes time to read through the topic and work it out but it seems very doable. Keep in mind it's probably much easier to find 2nd hand parts in the UK.
