I'm suspecting the reversing switch on my Mazda5 (2014, 1.6 Diesel) has died as reversing camera/light/sensor has stopped working apart from a random once in a blue moon.

Part looks cheap (£10-£15), but anyone able to offer any hints as to where it is located and how to get to it? Mazda seem to delight in burying things these days.

Or any other suggestions for things to check here welcome.
