Solution

1. Preparation

Gather tools: OBD-II scanner (if necessary), a flathead screwdriver, and a multimeter.
Ensure the vehicle is parked with the ignition turned off.

2. Check Software Updates

Turn on the ignition and access the infotainment system.
Navigate to “Settings” > “About” > “Software Update.”
Follow prompts to download and install any available updates via Wi-Fi.

3. Inspect Fuses

Locate the fuse box (typically under the dashboard or in the engine bay).
Use the owner’s manual to identify the fuse related to the infotainment system.
Remove the fuse using a fuse puller and visually inspect it; replace if blown.

4. Reset Infotainment System

Press and hold the power button on the infotainment unit for about 10-20 seconds.
Wait for the system to reboot and check if the issues persist.

5. Factory Reset

Navigate to “Settings” > “System” > “Factory Reset.”
Confirm the reset and wait for the system to restore to factory settings.

6. Check Battery Voltage

Use a multimeter to check the battery voltage; it should be around 12.6 volts when the vehicle is off.
If the voltage is low, charge or replace the battery as needed.
