dudu-lai Ok, I've got my reverse camera plugged into the "Cam In" on the rear of my DUDU7, that works ok. I've just wired up the 2nd camera and plugged it into the "CVBS In" and opened the "AUX" app - no good, no signal. Am I on the right track? There are no other video in cables from the DUDU7 so not sure what I'm missing π€¦
