Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, and a fuse puller.
Ensure the vehicle is parked in a safe location and the ignition is turned off.

2. Battery Check

Use the multimeter to measure the battery voltage.
If the voltage is below 12.4 volts, charge the battery or replace it as necessary.

3. Soft Reset

Locate the power button on the infotainment unit.
Press and hold the power button for approximately 10 seconds until the screen goes black and then reboots.

4. Fuse Inspection

Open the fuse box cover, typically located under the dashboard or in the engine compartment.
Identify the fuse related to the infotainment system (refer to the owner’s manual for the exact location).
Use a fuse puller to remove the fuse and inspect it. If the filament is broken, replace it with a fuse of the same amperage.

5. Software Update

If the system remains unresponsive, check for available software updates.
Visit the manufacturer's website or dealership to download the latest software onto a USB drive.
Insert the USB drive into the infotainment system and follow the on-screen instructions to update.
