A plug-and-play fibre optic decoder box for cars with the factory COMAND APS NTG 2 or NTG 2.5 system, such as the Mercedes-Benz ML, GL and R Series (2005-2011). Fitted with an aftermarket head unit, it lets the car's MOST bus sound system keep working.

  • Plug-and-play decoder for COMAND APS NTG 2 and NTG 2.5 (MOST bus) systems
  • For the Mercedes-Benz ML, GL and R Series 2005-2011, plus listed Porsche models
  • Takes stereo input from the head unit's front left and right RCA outputs
  • Won't decode the older D2B optical bus system (COMAND 2.0 and COMAND 2.5)

Keeps the factory fibre optic audio working

Cars with the factory COMAND APS NTG 2 or NTG 2.5 system send audio over a MOST fibre optic bus. Replace the head unit and the sound system needs a decoder to understand the new signal. This plug-and-play box does that job.

It can't decode the D2B optical bus system used by COMAND 2.0 and COMAND 2.5. Check your car's plug port to confirm which system you have before ordering.

When fitting, keep the fibre optic loop unbroken and leave original parts such as CD changers, satellite radio and phone modules connected. A bypass loop like the XTRONS ICE/ACS/FEXL009 is recommended if needed.

Connecting the head unit

The decoder takes stereo input only, from the head unit's Front Left and Right RCA outputs. Set the fader to the middle in your head unit's balance menu.

After installation, remove the sound system fuse for 15 minutes and then put it back to reset the system.
