Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, screwdriver set, wiring harness tools.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the vehicle's battery negative terminal to prevent electrical shorts.

2. Update Software

Reconnect the vehicle's battery and power on the infotainment system.
Navigate to the settings menu and select "Software Update."
Follow prompts to install any available updates.

3. Inspect and Repair Connections

Remove the radio unit using a screwdriver.
Check all wiring harness connections for damage or corrosion.
Clean any corroded terminals using contact cleaner and reconnect securely.

4. Check Battery Voltage

Use a multimeter to measure the battery voltage. It should read between 12.4V to 12.7V when the vehicle is off.
If the voltage is low, charge or replace the battery as necessary.

5. Hardware Reset

Power off the vehicle completely.
Hold down both scroll wheels on the steering wheel until the display resets.
Allow the system to reboot and check if the radio functions properly.
