Maintenance

To ensure the longevity and optimal performance of your SJOYBRING car stereo, follow these maintenance guidelines:

• Cleaning the Screen: Use a soft, lint-free cloth to gently wipe the QLED screen. For stubborn smudges, slightly dampen the cloth with water or a screen-safe cleaner. Avoid abrasive materials or harsh chemicals.
• General Cleaning: Keep the unit and surrounding dashboard area clean and free of dust. Use a soft brush or compressed air to clear debris from vents and buttons.
• Temperature Control: Avoid exposing the unit to extreme temperatures for prolonged periods. While designed for automotive use, excessive heat or cold can affect performance and lifespan.

Troubleshooting

If you encounter issues with your SJOYBRING car stereo, refer to the following common troubleshooting steps:

  • Check the vehicle's fuse box for blown fuses related to the radio or accessory power.
  • Verify all power connections (constant 12V, accessory 12V, ground) are secure and correctly wired.
• No Sound:
  • Ensure the volume is not muted or set too low.
  • Check speaker wire connections for proper polarity and secure contact.
  • Verify the audio source (Radio, Bluetooth, USB, CarPlay/Android Auto) is correctly selected.
• Bluetooth Connectivity Issues:
  • Ensure Bluetooth is enabled on both the stereo and your smartphone.
  • Delete previous pairings on both devices and attempt to re-pair.
  • Move your phone closer to the stereo to rule out signal interference.
• Backup Camera Not Displaying:
  • Check the video input connection (R-CAM) on the stereo.
  • Verify the reverse trigger wire is correctly connected to the vehicle's reverse light circuit.
  • Ensure the camera itself is receiving power.
• Touchscreen Unresponsive:
  • Perform a soft reset by pressing the RST button (if available) or disconnecting the vehicle's battery for a few minutes.
