Reversing Camera

[Sadsam]

Had my third Galaxy for 10 months now and the reversing camera has gone on the blink yet again! First time it went I had no graphic overlays (red, amber, green indicators) and the reversing sensors did not work. Second time the camera would just flash an image rapidly which made reversing at night very dangerous. And now I'm getting same issue as second time and also additional graphics that flash, these look like a distance as it changes ie. 0.90m, 0.50m this seems to be on the side that is closest to an object. Has any one else had problems? As my local garage is not very helpful. I'm thinking of taking it back and complaining as is can be dangerous especially at night as there is no way of switching it off.
