Reconnect the negative terminal and ensure it is secure.

4. Fuse Inspection

Locate the fuse box; refer to the owner's manual for the exact location of the infotainment system fuse.
Remove the fuse using a fuse puller or pliers and inspect it for any signs of damage (burnt or broken).
Replace the fuse with one of the same amperage if necessary.

5. Check USB and Connections

Examine the USB ports for dirt or debris; clean gently with compressed air if necessary.
Test with different USB devices to ensure compatibility and functionality.
