Solution

1. Preparation

Gather necessary tools: OBD-II scanner, trim removal tools, multimeter, and a soft cloth.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Battery Connections

Reconnect the negative battery terminal securely.
Check the positive terminal as well, ensuring it is tight and corrosion-free.
Use a multimeter to verify that the battery voltage is adequate (approximately 12.6 volts).

3. Check Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse for the audio system using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it's blown with a fuse of the same amperage.

4. Reset the Infotainment System

Turn the ignition to the "On" position without starting the engine.
Press and hold the power button on the infotainment system for 10-15 seconds until the screen resets.
Wait for the system to reboot and check if the radio functions.

5. Software Update

Connect the vehicle to Wi-Fi if applicable, or use a USB drive for updates.
Access the settings menu on the infotainment system and check for software updates.
Follow on-screen instructions to install any available updates.
