The Pioneer SPH-DA360DAB car radio can be installed in a 2012 Mercedes Vito W639, but it requires some precautions and possibly additional components.

- The car radio is a 2-DIN model, which is compatible with the standard dimensions of the Vito W639.
- However, it is important that you use the correct adapters and cable kits for installation in your specific vehicle model. These kits should allow control of the steering wheel controls, connection to any reversing cameras and other vehicle systems.
- Professional installation or careful planning is recommended to ensure that all functions are integrated correctly.

Before installation, you should therefore carefully check the necessary adapters and instructions and seek professional help if necessary.
