I have a SG9663DCPRO front and rear camera with a hardware kit and parking mode on.
The rear camera had stopped recording for several months, and I didn't know.
I troubleshooted by removing the front unit and the rear unit from my car. I checked both of them by plugging it into my computer, formatting the card, resetting the device, and upgrading the firmware to 1.17 (latest). When the front and rear are plugged into USB or a normal 12V outlet, both the front and the rear cameras work. They record just fine.
However, when taking it back to my car and plugging it back into my hardware kit, the rear camera doesn't turn on - only the front one records. I've ensured the setting is 3-WIRE, and that the display setting is "picture-in-picture". I do have the GPS connected.
I took the backup USB cord that connects the front and rear cameras (the one I used when plugging into the computer) and replaced the one in the car, but the rear picture still doesn't show, so it's not a problem with the connecting cable.
The hardware kit was wired correctly when I first installed it and I haven't touched it. The constant power lead is plugged into the door lock fuse (15A) and the accessory power lead is plugged into the mirror/cigarette lighter fuse (20A). The voltage protector is still set to 12V, the red light is still there too. What could be the problem? Possible blown fuse? Something else?
