SEALION 7 CarPlay or Android Auto not connecting

For SEALION 7 CarPlay or Android Auto problems, start with one unlocked phone and the connection method supported by your car. Check the data cable or wireless settings, then approve the projection prompts on both screens.

  1. Park and unlock the phone. Safety note: Set up while parked because screen changes distract from driving; keep factory resets and unofficial software out of this connection test, as they can remove settings or introduce unrelated problems.
  2. Temporarily switch off Bluetooth on other previously paired phones nearby.
  3. Choose the CarPlay or Android Auto connection method shown for your car.
  4. For wired use, connect a known data-capable cable to the vehicle’s USB data-transfer port.
  5. For supported wireless use, enable Bluetooth and Wi-Fi.
  6. Open the CarPlay or Android Auto application and accept the required prompts on both screens.
  7. Update the phone and projection components through their official stores.
  8. Keep the phone unlocked until the projection home screen appears.

What the result tells you

Bluetooth calls and phone projection are separate connections. A phone that charges over USB may still have no data connection. Wireless phone charging is also separate from wireless projection. If wired works but wireless fails, check wireless permissions, Wi-Fi and competing pairings.

If that did not work

If the supported connection still fails, remove only the affected pairing from the phone and car, restart normally and pair once again. Compare a second compatible phone and, for USB, a second data cable. If both supported phones fail, ask a BYD dealer to check projection support for the exact vehicle software and the failed USB or wireless path.

What to note down if you need support: phone model and operating-system version, full vehicle software version, wired or wireless method, exact message and which comparison worked. Keep an owner-confirmed workaround with its matching build conditions.
