What is this filter for? Is it compulsory to get it fitted?
I never fitter any filter in my previous cars (i10, wagonR, indica) nor any dealer told about this while service.
Also, as I said earlier, that I am having problems in reversing the car and I am confused between sensors and camera. Are the sensors enough, if yes then getting the sensors fitted from outside will void the warranty or not?
If I go for a camera, then can you suggest any cheap but good quality camera with screen that can play movies as well.
