Should be in 'camera' and if you're feeding it 12v and it's grounded correctly, it should technically switch straight over to camera as soon as you feed it live power.

Make sure your car is running, not sure why, but someone else had an issue not being able to get the camera to work, was testing with the ignition in position 2 and getting no result. Turned the car on and put it into reverse, it fired up fine.
