Hema Navigator 5", reversing camera, mirror image wiring? Help!

Thanks Dio. Will be in Brisbane end of month (1000 from home app) so will call see the guys at Johnny Appleseed on the industrial estate Salisbury (Salisbury used to be my area when I was an engineering products rep 100 years ago. Fun places there then*) as they sure know thrir products and give magic service. * Re Salisbury, one of my favourite calls was to an aluminum welding/engineering shop that made interesting compact landing barges with drop down ramps & cattle pens, to service cattle producers in the islands north of Australia. Bit like the one we went fishing in on our Cape York adventure that detoured on the way back to Weipa. This guy takes 4b's up the water ways and drops them off for a few days the, if they are good, picks them up again.
