Solution

1. Preparation

Ensure the vehicle is parked in a safe location.
Gather necessary tools: OBD-II scanner, small socket set, and a multimeter.

2. Check for Software Updates

Navigate to the "Software" section in the infotainment settings.
If an update is available, follow the prompts to download and install it.
Restart the system after the update is complete.

3. Inspect Battery Voltage

Use a multimeter to check the voltage at the battery terminals.
Ensure the voltage reads between 12.4V to 12.7V for a fully charged battery.
If the voltage is low, consider charging or replacing the battery.

4. Perform a Hard Reset

For a hard reset, hold down the "Volume" knob and "Scroll Wheel" simultaneously until the screen goes black.
Wait for the system to restart and check if the radio functions correctly.

5. Inspect Wiring and Connections

Remove the radio unit using a socket set to access the wiring harness.
Inspect all connections for signs of corrosion or damage.
Reseat any loose connections and replace corroded connectors as necessary.
