Maintenance

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

• Cleaning: Use a soft, dry cloth to clean the touchscreen and unit exterior. Avoid abrasive cleaners or solvents.
• Temperature: Avoid exposing the unit to extreme temperatures. The built-in heat sink helps dissipate heat, but prolonged exposure to direct sunlight or extreme cold can affect performance.
• Software Updates: Check the manufacturer's website periodically for any available software or firmware updates to ensure the best performance and compatibility.

Troubleshooting

If you encounter issues with your PLZ car stereo, refer to the following common problems and solutions:

Head Unit Powers On for a Few Seconds and Then Shuts Down Automatically

Some cars have ACC wires controlled by Canbus or feature a "delayed shut off" for radios. In such cases, the car may not output stable 12V power. Ensure the Red wire of your harness receives switched 12V power (car key must be turned on), the Yellow wire receives 12V power, and the Black ground wire is properly connected. If the ACC line (Red wire) and the B+ line (Yellow wire) are reversed, the product will lose its memory function after power is turned off.
