1. Preparation

Gather necessary tools: a USB drive (for backup if needed).
Ensure the vehicle is parked in a location with good GPS signal and Wi-Fi access.

2. Software Update

Navigate to the "Software" section in the settings menu.
If an update is available, connect the vehicle to a Wi-Fi network.
Follow the prompts to download and install the update. This may require the vehicle to be parked for a while.

3. Factory Reset

Go to "Controls" > "Service" > "Factory Reset".
Confirm the reset and allow the system to complete the process. This may take several minutes.
Reconfigure settings post-reset and check if navigation functions correctly.

4. GPS Antenna Inspection

If the navigation still does not work, inspect the GPS antenna.
This may require removing the trim around the antenna location, typically on the roof or rear of the vehicle.
Check for any physical damage, loose connections, or corrosion.
