Find the failure stage
| Symptom | Start here |
|---|---|
| Never enters CarPlay | Cannot connect → permissions, selected method, pairing |
| Works briefly, then restarts | Disconnecting → timing, handoff, overlays |
| All sound stays on phone / no guidance | No sound → media versus navigation routing |
| Music skips or cuts out | Audio stutter → video load, link comparison, diagnostics |
| Charging but no session | USB not working → data path, prompts, reported iOS combination |
| Fails creating wireless group | Wi-Fi Direct → Android version, API error, firmware radio support |

Use Settings → Diagnostics → Save diagnostic report after reproducing the problem. Android 10+ exports to Downloads/DiPlay; Android 9 uses a document picker.
Record exact app version, car/year, head unit/firmware, Android, iPhone/iOS, wired/wireless and hotspot/P2P method, plus time to failure. Review the log for identifiers before posting publicly.
A closed issue, a proposed PR, or a request to test an update does not prove the problem is fixed on your vehicle.
