Reverse camera

[Merc mat]

OK so after replacing my car battery, iv noticed that when you put car in reverse gear the camera does not come on ,iv checked the setting for it to come on when reverse is selected, any help would be appreciated also I can't open the camera on back ie to clean lens

Don't know what car but if you have auxiliary battery may be worth checking its condition also. They seem to screw with a lot of functions when down on power?
