If the fuse is intact, reconnect the battery terminal.
Remove the radio unit from the dashboard (use the appropriate trim removal tools to avoid damage).
Inspect the wiring harness connected to the radio for any loose connections or frayed wires.
Secure any loose wires and replace any damaged connectors.

4. Test the Radio

Reconnect the radio harness and reinsert the radio into its place.
Reconnect the negative battery terminal and turn the ignition to the "On" position.
Test the radio to see if it powers on.
