As the head unit powers on it runs through a series of checks, one of them being the reverse cam. It doesn't matter if you have no camera or not it will run through this test. During this test the head unit temporally turns on the reverse camera trigger circuit and your camera must be powered on for the head unit to see a camera and it will work form then on. In your case when you start your car in reverse there is power applied to the reverse light and turning on the camera so the head unit sees the camera is on and the test is good. When you start in neutral or another other gear no power to reverse light means no power to camera so the head unit reads this as no camera present. This is why your camera works when the car is started in reverse and does not work when started in any other gear.
In my 2013 Camry, head unit works the same as far as the reverse cam goes, I used a standard 5 pole relay. The switch circuit was the 6v reverse camera power from the head unit and the the power for the camera was from the cig light plug. This way when the head unit does its check it powers on its 6v reverse camera circuit, triggers relay, and then pulls 12v from the cig lighter. This way its good from then on. This 6v from the head unit is only on during this test and when the car is in reverse. The reason it's 6v is because Toyota uses 6v reverse cameras. The Reverse trigger wire hooked up normally, sounds like yours is fine.
There is a thread just for reverse camera installs, its pretty through. Read through that and you will find the proper way to hook up the camera.

You are right, I wired the cam dirrectly into the reverse lights, because it seemed to be easier at that moment. I will try to wire it the propper way
Thank you for your reply! Great idea with the relay btw.
