ATTO 3 CarPlay or Android Auto not connecting

Start with one phone and one method

1. Park safely and unlock the phone.
2. Confirm CarPlay or Android Auto is enabled on the phone and allowed for the BYD connection.
3. For wired use, try a known data-capable cable and the vehicle port identified for phone data.
4. For wireless use, keep Bluetooth and Wi-Fi enabled and remove conflicting temporary hotspots.
5. Accept prompts on both the phone and vehicle.

Re-pair cleanly

If it still fails, remove only the affected phone from both devices, restart the phone, then pair it once. Avoid a factory reset. Test a second compatible phone to separate a vehicle issue from a phone issue.

What to record

Note phone model, operating-system version, connection type, complete vehicle software version and the exact failure message.
