Ok so Joying Europe helped me, to remove the reverse black screen saying "No video signal" if you don't have rear camera, cut the orange wire from canbus to connector.
And for reverse beeping sound (front and rear snesor), just plug in the provided speaker in the joying unit box (little round speaker)
Citroen C5 X7 with RT3 radio from 2008/2009 are complicated, and the only way to keep the reverse beeping sound for front and rear sensor is to plug the provided speaker
You will not have the reverse beeping sound in the car speaker
