Confirm the car shows the iPhone as connected, then open CarPlay from the infotainment menu if required. A completed wireless pairing does not always mean the projection view opened automatically.
Use normal shutdown procedures, keep hardware dry and stop if you see damage, overheating, burning smells or any electrical risk.
Checks to perform in the right order
Confirm the exact symptom
Check that the vehicle has selected CarPlay as the active smartphone-projection source.
Start with the simplest reversible check
Launch CarPlay manually once and note whether the interface appears or immediately returns to the car menu.
Change one variable at a time
Compare wired CarPlay or a second iPhone to separate automatic-launch behavior from general compatibility.
Cross-test before resetting anything
Write down what changes and what stays the same. A controlled comparison is more useful than several resets performed together.
Escalate with useful evidence
If the problem survives the safe checks, record the model, software version, warning shown and tests already performed before contacting support.
How to narrow down the cause
- A change after one controlled test is a useful clue; keep the other variables unchanged.
- If a second compatible device works in the same setup, focus on the first device rather than replacing everything.
- Stop if there is heat, liquid, physical damage, burning smell or electrical risk.
Official sources used
Procedures can vary by model, firmware or hardware revision. When your device differs, use the official manufacturer documentation for that exact model.
