2 Answers
Methods to address a car multimedia system that won't turn on: 1. Restart the car and the navigation device; 2. Uninstall unnecessary software from the navigation device; 3. Replace the navigation device's motherboard if it has quality issues. The car multimedia system includes functions such as music and video playback, in-car WiFi, GPS navigation, and rearview camera. Common causes of car multimedia system failures are: 1. Poor contact in the power cable of the central control panel; 2. Abnormal power supply to the display screen; 3. Damaged display screen; 4. Blown fuse in the multimedia system. The method to flash the car multimedia system is: 1. Enter the system update option; 2. Click the three-dot button in the upper right corner to access the update menu; 3. Click "Manually Select Installation Package" and then confirm.
Last time I was driving, the multimedia system suddenly wouldn't turn on, and I almost missed an important navigation. I tried pressing the power button multiple times after starting the car, but there was no response - it was so frustrating. Later, a car-savvy friend told me that 90% of such issues are caused by either a blown fuse or software glitches. First, locate the multimedia fuse in the engine compartment's fuse box (usually marked in the manual), check if it's blackened or broken, and simply replace it with a new one. If the fuse is fine, then reset the system: turn off the engine, press and hold the center console's power button for 10 seconds to force a complete shutdown, then restart. Sometimes loose wiring connections can also cause this, like an unsecured USB port; I fixed my issue by cleaning the connector with a small cloth and reinserting it. Don't forget to regularly update the system software to prevent many malfunctions. If none of these work, the hardware might be damaged and need professional repair - never force it to avoid accidents.
