Yes, my problem was the camera it self.
I don`t know why but she doesen`t work in my radio unit. Maybe the resolution, i donīt know.
i was try a diferent camera in my radio and it work`s fine and my camera workīs fine in the other car whith a Pioneer radio.
My camera itīs on license plate whith Infrared, the other itīs a small camera like a park sensor. i donīt like it. i dont wanna drill the rear bumper.
for now i don`t have any camera installed yet.
if you have any friend whith a diferent camera, try it.
Your radio doesn`t have any problem.
Sorry about my english.
