Is it right for your car
This decoder box is for cars with the original COMAND APS NTG 1 system, which uses a MOST bus. It can't decode the D2B optical bus system used by COMAND 2.0 and COMAND 2.5, so check your vehicle's plug port before ordering.
Connecting it
The box takes a stereo signal from the head unit's front left and right RCA outputs only, so set the fader to the middle in your new radio's balance menu.
Keep the fibre optic loop unbroken. Leave original parts such as CD changers, satellite radio and phone modules connected, or use a bypass loop; XTRONS ICE/ACS/FEXL009 or ICE/ACS/fiberloop is recommended. Then take out the sound system fuse for 15 minutes and refit it to reset the system.
