Step 1: Check for Obvious Issues

Check for Updates: Look for a section labeled “Software Update” or “Map Update”. Ensure the system is up-to-date.

Power Cycle the System: Turn off the vehicle, wait a few minutes, and restart it. This can reset temporary glitches.

Step 4: Check GPS Antenna Connection

Inspect Antenna: The GPS antenna is usually located on the roof of the vehicle. Ensure it is not damaged or obstructed.
Check Wiring: If accessible, check the wiring for any visible damage or disconnections.
