Maintenance
General Care
To ensure the longevity and optimal performance of your car stereo, follow these general maintenance guidelines:
- Screen Cleaning: Use a soft, dry, lint-free cloth to clean the touchscreen. For stubborn smudges, lightly dampen the cloth with water or a screen-safe cleaner. Avoid abrasive materials or harsh chemical cleaners, as these can damage the screen coating.
