Remove or reset only the denied phone authorization from the infotainment menu, then reconnect with the phone unlocked. A rejected consent can look like a cable failure.
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
Identify whether the denial was on the phone or on the car display.
Start with the simplest reversible check
Clear the relevant phone projection permission and accept the expected prompt on the next connection.
Change one variable at a time
Compare the same phone after one clean reconnect and avoid deleting unrelated driver profiles.
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.
