Step 1: Perform a Basic Check
  • Symptom: The system is not powering on or is unresponsive.

Step 3: Restart the System
  • Symptom: System freezes or behaves erratically.
  • Action:
    • Turn off the vehicle and remove the key (or press the start button twice without pressing the brake).
    • Wait for about 10 minutes to allow the system to reset.
    • Restart the vehicle and check the navigation system.
Step 4: Check GPS Signal
  • Symptom: GPS not locking or showing incorrect location.

    • Disconnect any external devices and test the navigation system again.
