Do you have the just the head unit? Presumably you'll need the different facia panel as well, or did that come with it? Also, being a non GT Tech, does yours have the key start on the steering column? The (one piece) facia panel on my GT Tech includes a starter button.
I can't comment on how good the head unit is, it's not something I'm that bothered about, but I can confirm I can stream Spotify via Bluetooth.
