Ensure the vehicle is parked on a level surface.

Reconnect the vehicle battery.
Start the engine and access the iDrive system.
Navigate to "Settings" > "Software Update" and follow prompts to check for and install any available updates.

Locate the GPS antenna, typically found on the roof or near the rear of the vehicle.
Carefully remove any trims or covers to access the antenna.
Check for any visible damage or loose connections; reseat or replace the antenna as necessary.

Open the trunk and locate the navigation control unit.
Disconnect the unit by loosening screws and unplugging electrical connectors.
Clean any corrosion from connectors and reseat them firmly.
Reinstall the unit and secure it with screws.

With the vehicle running, press and hold the "Volume" button and the "Menu" button simultaneously for about 10 seconds until the system restarts.
Allow the system to reboot and check if the navigation functions correctly.

6. Recheck GPS Signal

Drive the vehicle to an open area away from tall buildings or trees to ensure the GPS signal is strong.
Monitor the navigation system to see if the issue persists.
