How to troubleshoot a navigation system issue on the Audi A4?

I'm having trouble with my navigation system on my Audi A4. It keeps freezing and losing GPS signal. How can I fix this problem?

Check for any software updates in the settings menu of your navigation system. Sometimes newer updates can fix bugs and improve performance.

If the software update doesn't help, try resetting the navigation system by pressing and holding the power button for 10 seconds. This can sometimes solve technical issues.

Make sure your car is parked in an open area with clear view of the sky. Tall buildings or dense trees can block the GPS signal and cause navigation issues.
