Mercedes-Benz GL450 worn volume and A/C buttons require full replacement and memorization of layout on Mercedes-Benz GL450

Some Mercedes-Benz GL450 owners report experiencing issues with worn volume and A/C buttons that necessitate full replacement and memorization of layout settings. These owners have found that using a repair kit can help restore the appearance of worn buttons, but for complete replacement, sourcing parts from authorized dealers is often recommended to ensure compatibility. Additionally, the GL450's memory function allows users to save up to three personalized settings for various seat adjustments, which may require reprogramming when new buttons are installed. Some owners appreciate the AC REST button feature, which enables them to turn off the air conditioning without shutting down the engine, but they may need professional assistance for complex tasks like button replacement and reprogramming to guarantee proper functionality.
