I have this in my Toyota;

It streams audio from the iPhone, not bad either. And does hands free phone as well.
But of course it's actually an FM transmitter not a Bluetooth streamer. But it is Bluetooth for the phone of course.
Drawbacks, hard to skip a track, no going back, no repeat track . And you have to have to have a dedicated FM station button for the device.
When the phone rings, you need to change to radio and the dedicated button to receive the call.
No voice control, no tack listing/readout.
A nice device, but. No substitute for the full voice control n the fiesta.
