1. Verify that our audio output cable has been correctly inserted in accordance with the instructions. For certain vehicles equipped with factory-installed AMI or AUX ports, the audio output cable must be connected to the vehicle’s original input interface.

2. Confirm whether the original vehicle system has switched to AUX mode or audio input mode.

3. If you have confirmed that the installation is correct yet there is still no sound via AUX, and if your vehicle’s original system supports Bluetooth audio streaming, please use Bluetooth to transmit audio instead. Connection Method: After connecting your mobile phone to CarPlay, return to the vehicle’s original system interface. Connect your phone to the car’s native Bluetooth system and switch the vehicle’s audio source to Bluetooth mode. Then, navigate to the device system settings: Settings > Phone Connection, and check the option labeled “Sound come from the car engine.” This enables audio transmission via the vehicle’s native Bluetooth system.

1. Verify whether the camera is an original factory unit or a modified aftermarket one; original factory cameras typically require no switch configuration by default.

2. Verify that the DIP switch settings are correct. Note: Each time the DIP switch settings are changed, the power cable must be disconnected and then reconnected to the device for the changes to take effect.

3. For certain manual-transmission models, the vehicle’s original system displays the reverse view correctly; however, the reverse view does not appear when using the CarPlay system. This requires manually connecting the reverse control wire. Simply connect the orange “REAR-C” cable—provided as a reserved lead on the module—to the 12V power source of the reverse light.

1. For certain vehicle models, the default configuration of the steering wheel control buttons is limited to volume adjustment and cannot be used to switch tracks (previous/next) while within the CarPlay interface. However, if your vehicle’s factory infotainment system supports Bluetooth audio streaming, you can enable track control functionality by switching to Bluetooth mode. Connection Instructions: After connecting your mobile phone to CarPlay, exit the CarPlay interface and return to your vehicle’s factory infotainment system. Next, pair your phone with the vehicle’s built-in Bluetooth system and switch the audio source on the vehicle’s system to “Bluetooth Mode” (rather than AUX mode). Subsequently, navigate to the device’s system settings interface (Path: Settings > Phone Connection) and check the option labeled “Sound from Vehicle Engine.” Once the above configuration is complete, the steering wheel control buttons will resume their normal functionality when audio is streamed through the vehicle’s built-in Bluetooth system.

2. Reasons for Vehicle Protocol Issues — If the original vehicle system does not support Bluetooth audio, steering wheel control functionality cannot be supported.
