I have the x920bt and the Audiovox ACA200W camera and having trouble getting it to work. My HU works great and I did a dry run with the camera before mounting by just running through VID1 input; worked fine. So, the camera is connected through the reverse lights for power, and video cable running to brown backup cam input on HU, then reverse wire from HU to the reverse wire circuit on vehicle. And I tested the reverse wire which is at 2 volts constant and 13.4 volts in reverse. But, nothing happens when I put the car in reverse. Camera setting is on and set to battery.
With all this in mind,
