Remove the fuse and inspect it for signs of damage. If blown, replace it with a new fuse of the same amperage.

3. Check GPS Antenna

Tools Required: Screwdriver set
Remove any trim or panels that obstruct access to the GPS antenna, usually located on the roof or rear of the vehicle.
Inspect the antenna for physical damage and ensure it is securely connected.
If damaged, replace the GPS antenna.

Visit the manufacturer’s website to find the latest navigation software for the XV50 model.
Follow the instructions for downloading and installing the software update onto the navigation system.
If necessary, connect the USB drive to the vehicle and follow on-screen prompts to complete the update.

5. Test Power Supply

Tools Required: Multimeter
Access the back of the navigation unit by removing the dashboard panel.
Use a multimeter to check for power at the navigation unit’s harness.
If the voltage is low or absent, trace the wiring back to the power source and repair any broken connections.

After completing any repairs or checks, reconnect the negative terminal of the battery.
Start the vehicle and check if the navigation system functions correctly.
If necessary, perform a factory reset of the navigation unit through the settings menu.
