Why is the car navigation not displaying?
2 Answers
Here are the specific reasons why the car navigation is not displaying: 1. Power supply abnormality: Check whether the power supply of the display screen is normal. If the power supply is abnormal, replace the power supply module. 2. Poor contact: Check whether the cable connection is good. If the line contact is poor, it is necessary to check whether there is a loose connection in the line in time, which causes the central control screen to go black. Just connect the loose part properly. 3. Display screen damage: Check whether the display screen is damaged. Replace the display screen for testing. If it returns to normal, the display screen is damaged. If the power supply is normal and the cable connection is good, check the video output signal of the motherboard.
Last time I encountered the navigation not displaying, and after struggling for a while, I found out it was because the ribbon cable behind the screen had come loose. After driving for a long time, bumps are inevitable, and if these connecting wires have poor contact, the screen will stop working. I've also experienced a situation where the navigation module got water inside, caused by the high-pressure water gun being too aggressive during car washing. The most troublesome issue is when the screen itself is broken, which requires dismantling the center console to replace the new screen. My suggestion is to first try restarting the car's infotainment system by holding down the power button for 10 seconds. If that still doesn't work, quickly go to a repair shop to check the wiring. Don't try to dismantle it yourself, as making it worse could lead to more trouble.
