5. Troubleshooting

5.1 Common Issues

• No Power: Ensure all power cables are securely connected. Perform the quick test described in Section 2.5. Check vehicle fuses.
• No Sound: Verify speaker connections. Check volume levels on the unit and ensure the mute function is not active. If the radio has no sound but USB/phone audio works, check wiring to the amplifier or contact support.
• Steering Wheel Controls Not Working: Ensure CANBUS connections are correct (if applicable) and perform key learning in settings. Refer to Section 2.4.2.
• Wireless CarPlay/Android Auto Connectivity Issues: Ensure Bluetooth is enabled on both devices. Check WiFi hotspot connection. For some Samsung/Huawei phones, functionality may be limited.
• GPS Signal Weak/Inaccurate: Ensure the GPS antenna is properly installed and has a clear view of the sky.

5.2 Advanced Troubleshooting for Toyota Prius with OEM Navigation

For Prius models with an original equipment manufacturer (OEM) navigation system, specific adjustments may be required:

• Steering Wheel Buttons: Disconnect the two middle wires from the Inefala harness 6-pin connector that interfaces with the car. These wires may incorrectly short SW1/SW2 signals. The four outer wires (often green and purple) should remain connected.
• OEM Backup Camera: The product does not provide a kit to reuse the OEM backup camera due to voltage differences (OEM is 6V, aftermarket is 12V). You may need to purchase a separate 16-pin harness designed for OEM backup cameras with aftermarket head units and a 12V-to-6V converter.
• Reverse Signal: For OEM nav systems, the reverse signal can be tapped at the 24-pin connector (often a pink wire). You may need to splice wires to connect this to the unit's flying-lead reverse signal wire.
• OEM GPS Antenna: The product does not provide a cable to reuse the OEM GPS antenna. An HFC-to-SMA adapter may be needed to connect to the gray HFC connector in the car.
• OEM Microphone: The OEM microphone module requires active power supply. A retrofit kit may not be available; consider using the microphone included with this product.
• Bluetooth and Wi-Fi Connectivity: Ensure the short video dongle with two short wires (antennae for Bluetooth and Wi-Fi) is plugged in.
• Camera and AUX Video Configuration (UJC201 systems):
  • Original Prius Backup Camera: In Factory Setup (password: 1234) > Backcar Source Settings, select CVBS.
  • Included Inefala Camera: In Factory Setup (password: 1234) > Backcar Source Settings, select AHD 720P 25fps.
  • Second Camera/Video Source: Uncheck "Settings > Car Settings > Hand Brake Detection" to allow video display.
  • CVBS Second Camera: Plug into RCA harness's CVBS-IN-1 or AUX VIN connector and use the AUX app.
  • AHD Second Camera: Plug into RCA harness's F CAM or CVBS-IN-2 connector. Set "Factory Setup > Camera Type Settings" to Common and "Car Settings > External input video signal" to "Front video". Use the "Front video" app. Both AHD cameras may need the same resolution and refresh rate.
