1. Check for Obstructions
Ensure you are in an open area with a clear view of the sky. Avoid tunnels, parking garages, or areas with tall buildings that can block satellite signals.
2. Restart Your Vehicle and System
Turn off your vehicle completely, wait for a few minutes, then restart. This can reset the GPS system and resolve minor glitches.
