Why choose Mr12Volt

Many cheaper Mercedes CarPlay boxes connect through the AUX input, which reduces sound quality. Mr12Volt connects through the Mercedes MOST fibre optic network and works with the factory screen, COMAND controller, steering wheel controls and sound system, so your SLK keeps its original sound and feel.
