I had the 360 camera on my 21, but not on the 23 and after living without it for the last 8 months I've realized how utterly useless the 360 really was. I still have the parking sensors in the front and still have the rear camera. And the rear camera display now shows on 100% on the top of the screen, whereas with the 360 it only went about 60% across the 360 took up the other 40%
What I miss more is the rear camera washer, now I have to actually get out and wipe off the camera lens so I can see the camera display. Before all I had to do was turn on the rear wiper washer and it would also spray on the camera, but ford took out the spray nozzle.
