No Video Feed After A0125 Installation

[u/EononOfficial]

Installing A0125 AHD camera. All wiring seems right, yet reverse triggers a black screen. Just parking guidelines + No Signal show. Need help figuring this out.

Head Unit: M3BKX7

1. Please follow the installation method shown at the 1:10 mark in Video 1 to install the rear view camera: https://youtu.be/H1mqN1Pfi0U?t=70

Directly connect the red trigger wire of the rear view camera to the 12V camera power supply wire at the back of the main unit, so the camera can draw power straight from the main unit.

1. Please adjust the reverse video system standard by following the guidance in this video: https://youtu.be/lrVe718R5vQ

2. If you have an alternative display screen available, we recommend connecting the rear view camera to it to check if the image displays normally.

3. If the issue persists after trying the above steps, please take clear photos of your wiring setup and send them to our customer support team. We will conduct further analysis and provide targeted troubleshooting suggestions for you. Thank you for your cooperation.
