This means I would either have had to put in a switch to power the camera when required or give it a permanent +12v supply, which causes the camera to get very hot. Hence using the reverse light feed to power it.

I even looked at tapping +12 out of the head unit but it was too much hassle and in warranty so gave up

I suggest you what connections your head unit has available and wire the camera accordingly... good luck
