I have a 2010 Mini Cooper Convertible R57. The display under the speedometer is starting to go bad. I read in the linked post that I can swap the speedometer & stereo with a unit from a 2011 to 2013 to get the display from a new vendor which will fix the issues , and should get me OEM Bluetooth that I don't currently have.

I found and swapped the speedometer & stereo from a 2011. And can link my phone for calls, but it doesn't give me the option for Bluetooth streaming. I talked the the OP in the linked post and they said for Bluetooth streaming music I would need a "little adapter". They also mentioned some "little tweaks to the coding" but they didn't elaborate, and I don't know what they meant about the adapter or coding.

Questions:

Is Bluetooth streaming even possible with these car radios? (Without a separate Bluetooth FM Transmitter)

There are some extra connections on the back of the new radio that my car doesn't have. Anyone know what they are? (I assume one is for a Sat. Radio antenna)
