I recently purchased your MQB to PQ ISO quadlock adapter. I’m looking for a headunit that can support the OEM backup camera. The OEM backup camera uses that yellow connector seen in the picture below.
As of today, I have not found an adapter that can solve the signal conversion problem. Your original camera had four wires in the harness. But the cvbs camera has only two wires in the harness. The RCD 330 plus only supports cvbs cameras. In any case, the price of a new camera is no more expensive than finding an adapter. So I recommend you to buy a new set of cameras.
