Hi.I did a retrofit (passat b8 360 degree camera), do you know how to insert a control module with the other modules on the car. the control module is a part from another car. the 5F (9.2 inch) control module is from another car and the 6C control module together with the rear and front camera (wide view), from another car. can you please tell me how to make it work. I activated VSP but I have a black image and the display lasts for a few seconds and then disappears. in order to make it open again that display from the top view, I have to close the ignition and quickly open it if it doesn't work anymore.
