Hello, how do I connect the reversing camera to the Blaupunkt New York 830? I connect the red to the reverse cable and the black to the ground, and the yellow chinch to the radio on the back of the chinch yellow with the inscription camera and after throwing the reverse gear nothing happens (What could be the reason) . I still have a question about the yellow China cable because two sides stick out about 10cm red cables. What are they for? Thank you for any help.
