Mr12Volt Mercedes-Benz MOST Bus NTG 4.5 and NTG 4.7 CarPlay and Android Auto Interface. High-end digital CarPlay upgrade for Mercedes with fibre optic audio and TV source integration.
Part Number: P2000-NTG45MM
Upgrade your Mercedes-Benz NTG 4.5 or NTG 4.7 system with Mr12Volt P2000-NTG45MM and enjoy Apple CarPlay and Android Auto the way it should be. Unlike AUX-in based adapters that compromise sound, this interface runs on the Mercedes MOST fibre optic bus and uses the factory TV video input for true digital to digital audio.
