This might be a naive question but can you activate enhanced Bluetooth or voice control via this interface or is there some additional hardware involved?
In hindsight, I am surprised that audio streaming over bluetooth is not standard these days - I have been overseas for most of the last month and all three hire cars I have used have had this feature (and they were crappy cars)!
