Identify whether the phone is not detected by USB, not listed over Bluetooth or listed but blocked from projection. Test one connection mode at a time with the vehicle parked.
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
Choose the connection type you are troubleshooting and avoid mixing USB and wireless tests in one attempt.
Start with the simplest reversible check
Check the documented data port, cable or Bluetooth pairing and note whether the phone still charges or appears in the device list.
Change one variable at a time
Compare a second compatible phone and verify that smartphone projection is enabled in the infotainment menu.
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.
