What is the reason for the black screen flickering issue in BYD Song's multimedia system?

[Emersyn]

It is likely a wiring issue. Check if the screen's wiring harness is loose. Inspect whether the contacts are normal, and carefully examine the wiring connections at the navigation device's ports to see if the vibration during driving caused the wiring ports to loosen and detach. Solutions: 1. Check the navigation software: Verify whether the navigation device's software is genuine or pirated. If it is pirated software, compatibility issues may arise, requiring the reinstallation of genuine software to resolve the problem. 2. Determine if it is caused by an upgrade: After upgrading the navigation device, some issues may occur, mainly because the original device may not fully support the new version of the software. In such cases, contact the manufacturer to replace the navigation device body for a solution. 3. Reset button: There is a reset button near the disc slot of the navigation device. Gently press it with a toothpick or a paperclip to reset and restore normal functionality.
