# Vehicle compatibility checklist — BYD Seal EV AWD Excellence (Türkiye)

Run every step **parked, in P, with the parking brake on**, except section F, which needs a passenger operating the
screen while someone else drives. Record results in the table at the end and attach the exported diagnostics report.

## A. Install and environment

- [ ] Note the multimedia software version (Settings › System) and DiLink generation.
- [ ] Install via the factory USB installer (INSTALL.md). Note any installer message verbatim.
- [ ] Open SEAL APEX and complete the first-run wizard.
- [ ] Garage › Compatibility & diagnostics › Export report. Keep both files.
- [ ] In the report, confirm `byd.present` and list the classes reported as `true`.

## B. Launcher safety

- [ ] The BYD button opens the factory home screen; HOME returns to SEAL APEX only if it is the default.
- [ ] Changing the default home back to BYD works (UNINSTALL_AND_ROLLBACK.md).
- [ ] Reverse gear: the factory camera appears on top of SEAL APEX; the floating HUD (if enabled) disappears.
- [ ] Incoming call, voice assistant and OEM warnings appear above SEAL APEX.
- [ ] Rotate the screen to portrait and back: layout adapts and media keeps playing.
- [ ] Restart the car: no boot loop; SEAL APEX starts only if you enabled autostart.

## C. Read-only signals (compare with the factory cluster)

| Signal | SEAL APEX value | Cluster value | Provenance tag | OK? |
|---|---|---|---|---|
| Speed (drive slowly with a passenger) | | | | |
| Gear P/R/N/D | | | | |
| SoC % | | | | |
| Range | | | | |
| Recent / average consumption | | | | |
| Odometer | | | | |
| Tyre pressures FL/FR/RL/RR | | | | |
| Door open (open each door) | | | | |
| Boot / bonnet open | | | | |
| Window open | | | | |
| Lock state | | | | |
| Outside temperature | | | | |
| PM2.5 inside/outside | | | | |
| 12 V battery | | | | |
| Turn signals | | | | |
| Charging: gun type, kW, time, kWh (at a charger) | | | | |

Values that cannot be read must show **NO DATA**, never a number.

## D. Climate commands (comfort only)

For each command: tap once, wait 2 s, compare with the factory climate screen.

| Command | Result on car |
|---|---|
| Power on/off | |
| Driver temperature ±1 | |
| Passenger temperature ±1 (dual zone) | |
| Sync / dual zone | |
| Fan 1–7 | |
| AUTO | |
| Recirculation | |
| Front / rear defrost | |
| Airflow modes | |
| Pet mode (sets 22 °C, AUTO) | |

## E. Media, navigation, HUD

- [ ] Grant notification access; play music in the factory player and in a third-party app; check title, art,
      controls and seek.
- [ ] Start a route in Google Maps / Waze / Yandex; check next-turn distance and arrow in the home map card, Apex
      Drive and HUD.
- [ ] Speed limit and camera chips appear only where OSM has data.
- [ ] Centre-screen HUD: Classic, Minimal and Navigation styles; long-press exits.

## F. Driving behaviour (passenger operates the screen)

- [ ] Status chip changes to DRIVING; Grand Tourer is replaced by Apex Drive.
- [ ] Garage is locked; search fields are disabled.
- [ ] No animation of the car while moving (default).
- [ ] At a red light in D the state stays DRIVING.

## G. Performance (optional, via ADB)

```bash
adb shell am start -W app.sealapex/.MainActivity        # TotalTime = cold start
adb shell dumpsys gfxinfo app.sealapex framestats       # frame times
adb shell dumpsys meminfo app.sealapex                  # memory
adb shell top -n 1 | grep sealapex                      # CPU
```
