Here are the solutions for the black screen issue in Elantra's navigation system: 1. Professional handling: Remove the entire central control screen assembly of the Elantra. Friends with insufficient DIY skills are advised to leave this step to the repair shop technicians, as improper handling of the plastic clips on the central control screen can easily cause them to break. 2. Blow dryer method: Use a hot air blower to blow on the CPU shown in the diagram for a few minutes, then let it cool naturally. The black screen issue in Elantra's navigation system is precisely caused by poor CPU connection, leading to a phenomenon of cold solder joints. This problem has appeared in many Elantra models and can be considered a common issue. 3. General solution: The black screen issue in Elantra's navigation system is relatively easy to solve. Therefore, when visiting a repair shop, you should first ask the technician to try the above methods to avoid immediately replacing the central control screen. Overall, the Hyundai Elantra is still a recommended model. Although it doesn't have many outstanding features in terms of performance, its fuel economy and reliability are quite good, which are the most important aspects for a family car.

I'm quite addicted to fixing cars myself. I've dealt with the Elantra's navigation screen blackout issue. First, test the power supply voltage: use simple tools to locate the main power cable connector of the navigation system and check if the 12V is stable without significant fluctuations, indicating normal power supply. Otherwise, inspect the fuse box and replace any faulty fuses. If there's power but the screen remains black, perform a hard reset by disconnecting the battery's negative terminal for ten minutes, then reconnect it to reset the software—this usually brings it back to life. If that doesn't work, remove the center console panel to check if the backplane ribbon cable is loose; reinsert and secure it to test the effect. If the problem persists, don’t force it to avoid short circuits—either buy a new module online to replace it or take it to a professional shop to save trouble. For prevention, regularly clear system cache and log files to reduce load and avoid memory overload crashes. Since the navigation module has poor heat dissipation, adding a small fan can improve cooling and prevent overheating blackouts.
