Disconnect the 12V battery to avoid electrical shorts during servicing.

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the trunk).
Identify the specific fuses related to the radio and audio system (refer to the user manual).
Remove the fuses and inspect them for continuity. Replace any blown fuses with new fuses of the same amperage.

3. Reset the Infotainment System

Reconnect the 12V battery.
Start the vehicle and wait for the systems to boot.
Perform a soft reset if the radio still does not function by holding down both scroll wheels on the steering wheel until the screen goes black and the Tesla logo appears.

4. Software Update

Go to the settings menu on the touchscreen.
Check for any available software updates.
If an update is available, follow the prompts to download and install it.

5. Test the Audio System

Once the system is reset and updated, test the radio by turning it on and checking all functionalities (AM/FM, Bluetooth, etc.).
Ensure all settings are appropriately configured for audio output.
