Hi guys i worked out how to make the reverse camera operate while in Drive , but now i want to add an additional camera for longer distance viewing ( like above the trailer ).
I tried wiring in a $20 ebay camera ( which works off 12v ) but the factory head unit does not recognise it , or the signal which comes out of it , whichever.
I know the factory camera works off 6v - this voltage is there all the time , and only goes off 20 seconds after the IG is switched off.
But does anyone know the difference between signal types , or protcols , whichever , between the older style ebay cameras and the factory type?
thanks in advance
