On the lower right by the AUX button on the faceplate is a three-letter code. In 2009 the only one with NAV was the RER (730N). In 2011 they offered two NAV radios, the RHB (430N), and the RHR (730N), an "upgraded" RER. All are compatible with the 2009, as long as they are high-speed bus. The RHB uses an external uConnect module, the RER\RHR have internal uConnect.
That white plug is not for the backup camera, the camera connects to the 22 pin connector next to that white socket.
This site will show you the radio connections, once you put in the year and model, do a search for radio
There was a complete OEM kit you could buy, 82211184, not sure if it's still avaialble though.
