So far so good

Don't want to tempt fate, but had the Rangy for a couple of weeks now and so far so good. Absolutely love driving it around. Done a couple of jobs already. Changed the non return valve for the rear wiper and cleaned the jets. The dealer fitted a new battery but the mechanic couldn't get both the securing screws in (he didn't even know about the service position for the bonnet, so I watched him struggle) so I sorted that. I've also cleaned and re coloured the two front seats and I'm pleased with the results. The only job left is to sort the reversing cam. I've had it in bits and I was surprised to see a circuit board in the housing. Does anyone know what it does, and will I be safe to replace the OK cam with an aftermarket one? Will the lack of the circuit board on the replacement cause any issues. I plan to use the original power and video cables, just swap the camera.
