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.

Having worked on cars for so many years, I've encountered many instances of the BYD Song's infotainment screen flickering or going black. This is usually caused by several common issues: aging or damage to the screen itself, especially during hot seasons when poor contact becomes more likely; loose wiring connections, such as improperly secured cables for the rearview camera or USB ports interfering with display; software system bugs, where frequent updates or poorly compatible apps cause conflicts; or unstable voltage, where low battery power or alternator issues lead to insufficient power supply. If the screen flickering is accompanied by the disappearance of the reverse camera feed, it's likely a hardware failure. I recommend owners first try restarting the system by holding down the infotainment button or disconnecting the battery for a few minutes to reset it. If that doesn't work, it's best to visit a professional shop for diagnostic tool checks rather than attempting DIY repairs that might damage more components. Parking in shaded areas to avoid direct sunlight can also slow screen aging, and keeping the system firmware up to date is crucial.

I've been driving this Song for two years and have encountered issues with the screen frequently flashing or going black, which is quite annoying. The most common problem is system instability after a failed software upgrade, such as navigation maps freezing or music app conflicts. Sometimes, restarting a few times can fix it. On the hardware side, it might be a faulty screen backlight or loose ribbon cable connections, especially on bumpy roads where the shaking is more pronounced. Power-wise, if the battery is low or there's voltage fluctuation during startup, the infotainment system can also behave abnormally. For DIY fixes, you can try unplugging all external devices or resetting the system to factory defaults in the settings. At the dealership, they usually test the graphics card or motherboard, and if the cost isn't high, it's best to get it repaired promptly. Using more OEM parts and avoiding third-party accessories can reduce such troubles. Remember to regularly clear the cache to maintain smooth operation.

As a young car enthusiast who frequently uses in-car entertainment, the black screen flickering issue in the Song's multimedia system could be caused by system overload, such as running navigation and gaming apps simultaneously; accelerated aging of the screen graphics card; or loose connections/dusty interfaces. A simple restart or software update should fix it. To protect the screen, minimize multitasking operations on the infotainment system during daily use.
