Maintenance

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

• Cleaning: Use a soft, dry cloth to clean the touch screen and unit exterior. Avoid abrasive cleaners or solvents.
• Software Updates: Periodically check for and install any available software updates to ensure the system runs efficiently and securely.
• Environmental Conditions: Avoid exposing the unit to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture.
• Wiring: Ensure all wiring connections remain secure. If you experience intermittent issues, check the connections.

Troubleshooting

If you encounter issues with your Toeeklsa Car Radio, refer to the following common problems and solutions:

• No Power:
  • Check all power connections and fuses.
  • Ensure the vehicle's battery is fully charged.
• No Sound or Distorted Audio:
  • Verify speaker connections.
  • Check audio settings (volume, balance, fader, equalizer).
  • For Bose "Lux" Amp Equipped Vehicles (RPO code Y91): If experiencing static or hissing, the factory low-level line inputs may be overdriven. Consider splicing a high-to-low level adjustable line converter into the included harness (left-front & right-front, + and -) and using an RCA cable to connect to the converter's output, then splicing the RCA cable's cut end to the harness speaker wires. This allows adjustment to prevent overdriving the amp.
• CarPlay/Android Auto Not Connecting:
  • Ensure Bluetooth and Wi-Fi are enabled on your smartphone.
  • Forget the device from both the car radio and your phone, then attempt to reconnect.
  • Update your phone's operating system and the car radio's software.
• GPS Signal Issues:
  • Ensure the GPS antenna is properly installed and has a clear view of the sky.
  • Check Wi-Fi connection for online map services.
• Steering Wheel Controls Not Working:
  • Verify the SWC wiring connections.
  • Access the unit's settings to configure or recalibrate the steering wheel controls.
