BYD CarPlay Troubleshooting Guide

This troubleshooting guide is built from real support conversations with BYD owners.

If CPLHan isn't working right, start here. Most issues are fixed in under 5 minutes.

CarPlay doesn't appear on the screen

1. Make sure Bluetooth is ON on your iPhone and it's paired with the car.
2. Close the app on the head unit, then reopen it.
3. Restart both the head unit (turn car off and on again) and your iPhone.
4. Check the app is running on the car screen, not just installed.

App stuck on the 7-day trial screen

This means the app can't reach the activation server on first launch. Fix:

1. Turn on your iPhone's personal hotspot.
2. Connect the BYD head unit to your iPhone's hotspot (or any Wi-Fi).
3. Reopen the app. It should pass the trial screen within a minute.
4. Once the trial loads, you can turn off the hotspot. CarPlay itself does not need internet.

Video or audio is laggy during the trial

Slight lag during the 7-day free trial is normal. The app downloads and processes CarPlay data in the background. After activation, it runs smoothly.

To improve performance:

• Close other apps running on the head unit.
• Make sure your iPhone has a stable Bluetooth connection.
• Move closer to the head unit if there are obstructions.

No sound through the car speakers

1. Check the car's audio source is set to Bluetooth or the correct input.
2. Turn up the volume on both the car and your iPhone.
3. Restart the app on the head unit.
4. If using navigation, make sure the navigation app's volume is up in your iPhone settings.

Navigation doesn't show on the car screen

1. Make sure Apple Maps or Google Maps is installed on your iPhone.
2. Open CarPlay on the car screen, then select the navigation app from the CarPlay home screen.
3. If the navigation app doesn't appear, restart the connection.

Connection drops randomly

• Check that other Bluetooth devices aren't interfering.
• Forget the car on your iPhone's Bluetooth settings, then pair again.
• Make sure the app is allowed to run in the background on the head unit.

App won't install from the browser

Some BYD head units block browser downloads. Fix:

1. Copy the APK file to a USB drive.
2. Plug the USB into the car.
3. Open the file manager on the head unit and install from USB.
4. If prompted, enable "Install unknown apps" in Settings → Security.

Permissions denied

During setup, the app may ask for Bluetooth, Wi-Fi, and location permissions. Please allow all of them — they are required for the connection to work. You can revoke location after setup if you prefer.
