How do I troubleshoot an issue with my Vauxhall Grandland's navigation system?

I've been having trouble with my navigation system in my Vauxhall Grandland. It keeps freezing and giving me incorrect directions. What steps can I take to address this issue and ensure my navigation system is functioning properly?

First, try resetting your car's infotainment system by holding down the power button for 10 seconds. If that doesn't work, try updating the navigation maps using the system's built-in update feature.

If the issue persists, you may need to bring your Vauxhall Grandland to a dealership for further diagnosis. It's possible that there is a hardware problem that needs to be addressed.
