SEAL CarPlay or Android Auto not connecting

Build a clean test

1. Park the SEAL, power it on and confirm the phone is unlocked with Bluetooth and Wi-Fi available where the chosen connection requires them.
2. Restart the phone and centre display normally.
3. For USB testing, use a known data-capable cable and the vehicle data port, not a charge-only socket.
4. Remove the SEAL from the phone’s CarPlay or Android Auto list and remove the phone from the vehicle device list.
5. Pair again, accepting projection, contacts, notifications and microphone prompts needed for the feature.
6. Test navigation audio, music and one safe stationary call, then confirm sound returns to the expected source.
7. If a second compatible phone works, review the first phone’s operating system, restrictions, VPN and app permissions.

What the result means

• Charging but no projection: suspect a charge-only cable, wrong port or permission.
• Calls work but media is silent: select the intended vehicle audio source and check phone media volume.
• It fails only after an update: save the complete SEAL and phone software versions before resetting pairings again.

Do not factory-reset the vehicle as a first step. A repeatable failure with two compatible phones and known-good cables should be documented for BYD support.
