There is a restart hole near the SD card. If restarting doesn't work, replacement may be needed. The car display screen has a small restart hole on the panel. Use a toothpick to press the internal switch for a few seconds to restart.

I've encountered screen freezing issues a few times while driving my Volkswagen Sagitar, and the restart method is quite simple. Usually, first try holding down the power button on the display for 10 to 15 seconds, don't release until the screen goes black and then lights up again. If that doesn't work, you'll need to disconnect the power. Open the hood, locate the battery, loosen the negative terminal clamp, wait 5 to 10 minutes to let the system fully discharge, then reconnect and start the car. This can clear the software cache and resolve temporary glitches. I also recommend checking if the vehicle is parked in a shaded area to avoid overheating that may cause freezing. It's best to regularly visit the 4S shop for system updates to reduce such issues. Make sure the car is turned off and parked safely before performing these operations. If freezing occurs frequently, it might be a hardware issue, and sending it for repair would be more cost-effective.

Restarting a frozen Volkswagen Sagitar screen is not difficult. After turning off the engine, press and hold the power button for 15 seconds to force a shutdown, then turn it back on. If that doesn't work, perform a power reset: remove the negative battery cable in the engine compartment, wait 5 to 8 minutes to fully discharge the voltage, reconnect the clamp, and start the car. This process is relatively quick but slightly complex for beginners—take your time and stay calm. I've fixed occasional screen freezes in my car this way, and it usually recovers. Be careful not to touch metal parts during the power reset to avoid short circuits. For prevention, maintain good ventilation inside the car to prevent the infotainment system from overheating. If the issue persists after restarting, visit a professional repair shop early to avoid distractions while driving, which could be unsafe.

The method to reboot a frozen Sagitar display is straightforward. Turn off the engine and press the power button for more than 10 seconds until the screen restarts. If that doesn't work, disconnect the negative battery terminal, wait a few minutes, then reconnect and power on. The operation is simple, quick, and safety is the priority. Freezes are often caused by minor software glitches, and this method can reset the system. However, ensure the vehicle is parked and don't rush. If the issue persists frequently, consider a system upgrade or a 4S inspection to prevent potential hazards.
