Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, and a flathead screwdriver.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the vehicle's 12V battery to prevent any electrical issues.

2. Inspect Audio System Connections

Remove the dashboard cover to access the audio system wiring.
- Use a flathead screwdriver to carefully pry off the cover.
Check all electrical connectors leading to the audio unit.
- Ensure all connectors are securely attached and free of corrosion.

3. Test Power Supply to the Audio Unit

Reconnect the 12V battery and turn on the ignition.
Use a multimeter to measure the voltage at the audio unit’s power connector.
- Expected voltage: approximately 12V.
- If voltage is low or absent, trace the power wire back to the source for damage.

4. Update Audio System Software

Reconnect the vehicle’s battery and power on the infotainment system.
Go to the settings menu on the touchscreen to check for software updates.
- If an update is available, follow the prompts to download and install.

5. Check Speaker Functionality

After performing updates, test each speaker individually for sound output.
If specific speakers are still not functioning, consider replacing them.
