I figured it out and its working now.

My wiring is correct.

Nowdays some HU have a reverse signal in wire that detects a reverse signal.

Just need to hotwire that to the 12v reverse signal. Done. Case closed :)

Yes, I can answer that, have look at your 20 pins connector, on pin 5 is reverse signal , Pin 11 is Video (+) , pin 12 is video(-) , pin 13 is camera (+) (6V) and pin 14 is Camera (-) (6V) , with pin 13 & 14 make sure you convert them to 6V before you hook up to ur factory Camera unit otherwise you may cause permanent damage to your device.

any problems pls contact me.

cheers

I recently bought an android aftermarket Head unit and came across this problem as well when trying to connect the stock reverse camera to the after market HU. 

Below is my 20 pin connector from my 2010 Camry hybrid. Looks identical to Peter Yeh's. I'm using his wire identification above. 

It didn't work after 2 tries, I haven't soldered it into place yet as I'm not sure it's right. I have a 12v to 6v converter from Jaycar as well. Here's my connection:

pin 5 (red) reverse signal -> 12v in

pin 11 Video+ (red) -> RCA+ (middle lead)

pin 12 Video- (white) -> RCA- (outside lead)

pin13 Camera+ (black) -> 6v out

pin 14 Camera- (black) -> short to ground with main connector (brown) from the large bunch of wires from the other connector head. 

I short the 12v-in ground with the 6v-out ground with pin 14 and the brown ground wire from another connector. 

Is this right? With the RCA plugged into the HU, nothing happened when I shifted into reverse gear. 

I know this thread is old, but any experts still around?
