Methods to turn off the navigation screen that remains on after engine shutdown: 1. Press and hold the power button on the navigation system; 2. If it still doesn't turn off, you can restart the car by turning off the navigation first and then shutting down the engine. The car GPS navigation system consists of two parts: one part includes the GPS receiver and display device installed in the car; the other part is the computer control center. These two parts communicate via positioning satellites. Working principle of the car GPS navigation system: 24 GPS satellites orbit the Earth at an altitude of 12,000 kilometers with a 12-hour cycle, ensuring that at any given time, any point on the ground can observe at least 4 satellites simultaneously.

I used to find the navigation screen staying on after turning off the car, which was particularly annoying because I worried about the battery draining or even getting damaged. So I figured out how to turn it off myself: Don’t rush—first, start the engine (or just power on the car), then enter the navigation system’s settings menu. Look for a section like ‘Power Management’ or ‘Display Options,’ where there might be a ‘Delayed Shutdown After Engine Off’ feature. It’s enabled by default for convenience when finishing navigation operations before leaving the car. Just turn it off or set it to ‘Shut Off Immediately,’ and you’re done. If the menu is complicated, try holding down the navigation screen’s power button for a few seconds to force a shutdown. Remember to check the vehicle manual, as the settings vary by model. My old car’s issue was resolved after adjusting this setting. Also, regularly turning off the screen helps protect the battery, avoiding startup difficulties from long-term parking. Driving periodically to recharge the battery can also prevent problems. My advice is not to delay fixing it, lest you end up spending money on a new battery.

When I first bought my car, I also encountered the issue where the navigation screen stayed on after turning off the engine, which I thought was a waste of battery and could potentially harm the car. The solution is quite simple: turn the ignition switch to the 'on' position without starting the engine, then operate the central control screen. Tap the settings icon, navigate to the user options or power-related section. Look for 'screen off time' or 'delay settings' and change it to zero seconds or turn it off. Some car systems are simpler and allow you to adjust it directly with a knob. After making the changes, test it by turning off the engine to confirm the screen turns off immediately. If the settings don’t take effect, it might be a software bug—restarting the vehicle's electronic system usually fixes it. You can disconnect the negative terminal of the battery for a few minutes and reconnect it (be careful not to touch the positive terminal), but I rarely use this method as I’m afraid of making mistakes. Remember, this delay function is originally designed to allow passengers to continue using the navigation, but turning it off is more convenient and prevents battery drain. For short trips, I’ve also developed the habit of manually turning off the screen before shutting down the engine.

It annoys me that the navigation screen stays on after turning off the engine and can't be turned off immediately, as it feels like it's draining power and potentially harming the battery. So I went to my car to try turning it off: start the engine or power on, click the screen to enter the main menu, scroll to settings, and look for power-related options. I found the 'Delayed Screen Off' switch and turned it off. Most modern cars have this setting, and after turning it off, the screen will go dark along with the engine. If there's no button, you can also force it off by long-pressing the screen's power button. The root of the problem is that manufacturers designed it for user convenience to finish operations before getting out of the car, but the delay is too long. My little trick is to manually turn off the navigation system before shutting off the engine, making it a habit to avoid forgetting. Occasionally, if the screen gets stuck and won't turn off, it might be a software glitch—just restart the vehicle and don't panic. In short, maintaining battery health is important, so drive frequently to keep it charged.
