Focus 2011 LW TDCI Sport Advice on upgrading to Genuine Sat Nav unit Sony set up

[mgc0407]

Hi I have a 2011 Focus LW TDCI sport and would like to remove the standard Sony radio and small monitor set up and replace it with the bigger screen i think 5 inch Genuine Ford Sat nav set up. My original system doesnt have sat nav so i wanted to know what parts are needed from the wreckers. I would also like to fit a reverse camera as it only has factory reverse parking sensors at the moment. Any help would be much appreciated as i dont really want to go down the aftermarket Android set up. Thanks Mark Caudwell
