Solution

1. Preparation

Ensure the vehicle is parked safely and in a well-ventilated area.
Gather necessary tools and parts.

2. Soft Reboot

Hold down both scroll wheels on the steering wheel until the screen goes black and then reboots (approximately 10-15 seconds).

Use a multimeter to check the voltage; it should be around 12.6 volts or higher.
If low, replace the battery with a new one (Type: Group 34 AGM).

4. Inspect Fuses

Locate the fuse box under the dashboard or in the front trunk.
Use a fuse puller to check the fuses related to the infotainment system (refer to the owner's manual for specific fuse numbers).
Replace any blown fuses with the same amperage rating.

5. Inspect Connectors

Remove the center console trim to access the infotainment unit.
Disconnect and reconnect the touchscreen and infotainment connectors.
Inspect for any corrosion or damage to the connectors; clean if necessary.

6. Software Update

Ensure the vehicle is connected to Wi-Fi.
Go to "Software" in the settings menu and check for any available updates.
Follow prompts to install updates if any are available.
