Fully erase your car’s CarPlay profile (the hidden menu fix)
Most people remove the phone from CarPlay settings, but NOT from the vehicle’s Wi-Fi memory, which is the real cause.
🔧 In your vehicle:
- Go to Car settings → Connections → Wi-Fi → Saved Networks
- Find your old iPhone 15 AND your new iPhone 17
- Delete ALL Apple/iPhone entries
- Turn the car off
- Open the car door (forces module to power-cycle)
- Wait 15 seconds
🔧 Now on iPhone 17:
- Settings → General → CarPlay
- Remove your vehicle
- Settings → Wi-Fi → Forget the vehicle’s network
- Settings → Bluetooth → Forget the vehicle
Now re-pair from scratch.
