Fitted a couple of Pioneer X560BT in our cars, looks like its been superseded by the X580 now. No CD so really tiny units, made chucking all the cables, steering wheel adaptors etc behind nice and easy. Sounded great and the hands free bluetooth was exceptionally clear (I think I read they use Parrot tech there).
It displays track names over Bluetooth, pretty sure I skip using the steering wheel controls, hold the main unit volume control in for a couple of seconds for Siri etc. The iPod control is excellent too with fast browsing by album, artist, genre etc.
