Portable CarPlay Screen Setup & FAQ

Make sure Bluetooth and Wi-Fi are enabled on your iPhone. Restart both your iPhone and HIEHA screen, then forget the old Bluetooth connection and pair again from the CarPlay setup screen.

Disconnection can happen when the phone switches networks, Bluetooth permission is blocked, or an old pairing conflicts with the new one. Delete the previous connection, keep Wi-Fi and Bluetooth on, and reconnect near the screen.

Most HIEHA portable CarPlay screens support wireless CarPlay. A cable may only be needed for charging your phone or for specific troubleshooting steps depending on the model.

Make sure your Android phone supports Android Auto and that Bluetooth, Wi-Fi, and required permissions are enabled. Restart the phone and screen, then pair again from the Android Auto setup mode.

Android Auto may require permissions for Bluetooth, location, notifications, microphone, and nearby devices. Allow the requested permissions so the phone can connect and display correctly.

Update Android Auto, restart your phone, clear old Bluetooth records, confirm Wi-Fi is on, and try reconnecting. If the issue continues, test with another Android phone to confirm whether the issue is phone-specific.

Check that the camera cable is firmly connected to the screen, the camera power wire is connected correctly, and the reverse trigger wire is installed according to the setup guide.

The reverse trigger signal may not be connected correctly. Check the reverse light power wire, camera wiring, and input settings. Watch the backup camera setup video before adjusting the wiring.

Check camera mounting angle, lens direction, and screen settings. If the image is upside down, mirrored incorrectly, or unstable, confirm the camera model and contact HIEHA Support with a photo or short video.

Check the screen volume, phone volume, and audio output mode. Depending on your setup, sound may come from the built-in speaker, FM transmitter, AUX cable, or original car Bluetooth.

You can usually use FM transmission, AUX input, or your car’s Bluetooth audio path depending on your vehicle and HIEHA screen model. Match the screen audio mode with your car’s selected audio input.

Choose a less crowded FM frequency, set the same frequency on the HIEHA screen and car radio, and avoid frequencies used by local radio stations.

Make sure your phone and HIEHA screen are connected through the correct Mirror Link or PhoneLink mode. Enable Wi-Fi, follow the on-screen instructions, and allow screen sharing permissions when prompted.

Wireless mirroring can be affected by phone performance, distance, Wi-Fi interference, and background apps. Keep the phone close to the screen and close unnecessary apps before mirroring.

No. CarPlay and Android Auto provide an in-car interface for supported apps. Mirror Link displays your phone screen. Use CarPlay or Android Auto for driving-friendly navigation and media when possible.

Visit the HIEHA app download page for compatible app and support resources. Make sure you choose the correct download or support instructions for your product model.

Follow the online upgrade video or firmware guide for your screen model. Keep the device powered during the update and do not disconnect the screen while the upgrade is in progress.

Prepare your order number, product model, purchase channel, photos or a short video of the issue, and a clear description of what you tried before contacting HIEHA Support.
