How it works

• Mr12volt is selected through TV features of Mercedes NTG 4.5 / 4.7
• No coding tools or Factory TV module is needed, once Mr12volt CarPlay module is installed successfully (pressing both "Return" and "C" buttons will activate the "TV" option in menu)
• Supports aftermarket cameras up to AHD720
• Supports the integration of OEM microphone
• Both MB and Mr12volt Bluetooth can be connected at the same time. MB will handle as HF/call and Mr12volt as HF/Media (as a result, MB HF takes over Mr12volt when a call is received)
