    • Turn on the vehicle and the infotainment system.
    • Go to Settings > Apple CarPlay.
    • Ensure CarPlay is enabled.

  2. On the iPhone:

    • Press and hold the power button until the “slide to power off” slider appears.
    • Slide to power off, then turn it back on.

  2. Restart the Infotainment System:

    • Turn off the vehicle and wait for at least 1 minute before restarting.
    • This allows the system to refresh.
Step 4: Update Software
