With the ignition off, remove the key from the ignition slot.
Wait for at least 5 minutes before reinserting the key and starting the vehicle.
Check if the navigation system responds after the restart.

4. Inspect Battery and Connections

Use a multimeter to measure the battery voltage.
If the voltage is low, charge or replace the battery as needed.
Visually inspect and clean any corroded battery terminals or connections.

5. Replace Fuse (if necessary)

Locate the fuse box, usually found in the glove compartment or under the dashboard.
Identify the appropriate fuse for the navigation system using the fuse diagram.
Remove the faulty fuse using a fuse puller and replace it with a new fuse of the same amperage.
