This unit probably installs like the very similar Kenwood KMR-D562BT that I had at one time. CLICK
It is easy to wire up with the harness adapter as noted in the thread, the OEM radio has a different antenna socket to the Kenwood antenna so the an adaptor is required, if you are replacing the OEM navigation radio you do not need the adaptor as it is there already.
It matched the painted bezel and had a microphone for a hands free phone connection as well, well worth the extra 25 bucks or so.
