Mercedes NTG5 COMAND and Audio 20 Systems

V1.6 - Note that there are some head-unit photos missing, I will add as I get hold of the various units.


Mercedes introduced COMAND NTG5 in the W222 S-Class at launch in 2013. This systems was strangely known as NTG5*2 internally.  It was then installed in the W205 C-Class at launch and used on the GLC, AMG-GTS and the W447 Vito. The "non navigation" Audio-20, and the Garmin SD card "Audio-20 with Navigation" systems were also launched with the W205-C class. A version of the Audio-20 without a CD player was installed in earler W213/W238/W257 E and CLS vehicles.

NTG5*2 has no keyboard, and excepting the Audio-20 on E/CLS it does have a CD player (COMAND has a CD/DVD which is actually a BLU-RAY mech but i've never tried playing a BLU-RAY in it). It is controlled completely from a rotary controller and an optional touchpad (cars with COMAND always have the touchpad).  COMAND NTG5*2 is made by Harman. Audio-20 NTG5*2 is made by Mitubishi (Melco) or by Panasonic. The Panasonic unit supports Apple CarPlay and Android Auto and is known as NTG5ES2 internally, NTG5*2 has a seperate SD-Card/Twin USB connector in the centre armrest and DAB functions are provided by an external tuner.

A more traditional system with full keyboard was then released and this is called NTG5*1.  It was installed in the MY2015 E class and CLS class, and followed in the A, B, CLA, GLA and with the GLE/GLS when they were facelifted (and renamed from ML/GL). It has a SD-CARD slot in the front and seperate USB ports in the armrest glovebox and DAB functions are provided by an external tuner.

NTG5.5 was then introduced for the W213/W238 E Class and the CLS adding Apple CarPlay and Android Auto Support. At launch only COMAND was NTG5.5 and Audio-20 was NTG5*2,  Audio-20 was updated to NTG5.5 around the Model Year 2018 release - The NTG5.5 Audio-20 supports both the standard Audio-20 LCD and the larger LCD previously used for COMAND, and of course Apple CarPlay and Android Auto.  Note that NTG5.5 does not have an inbuilt CD/DVD player but there is an optional external CD/DVD that is in the main glovebox and can be retrofitted. NTG5.5 seems to be made only by Mitsubishi Electric (Melco). NTG5.5 systems have the DAB tuner built in and use the FM/AM antenna connection for DAB aswell.

There are two versions of the Audio-20, one that has inbuilt Navigation and a very basic one without Navigation and without a fibre optic port.   The navigation units used a SD card with Garmin maps and navigation software on it.  There are 3 different types of card (NTG5*1 / Panasonic NTG5*2, NTG5*2 Mitsubishi, NTG5.5), and for each type of card there are two variants, and update card to uprgade a vehicle that already has a SD card installed, and a full release for cars without the SD card or which the SD card has been lost.  Then there are a number of maps for different areas, Europe, India, South East Asia, etc etc.

Anti-Theft features

All NTG5 systems have a very long anti-theft code that must be entered using Xentry Diagnosis (the factory Diagnosis system) when a unit is put in a vehicle with a different 

Apple CarPlay and Android Auto Support

COMAND NTG5*1 and COMAND NTG5.5 can support Apple CarPlay and Android Auto.  Cars with NTG5*1 without these options will need a software update and a licence package purchased to be installed correctly.  Mercedes state that the warranty is void if you do not purchase the licence package - I assume this just applies to the Audio system. COMAND NTG5*2 can not support Car Play or Android Auto - even though the early press photos of Car Play showed it in a W205 C class.

There have been two manafacturers of Audio-20 units,  Mitsubishi and Panasonic.  The Mitsubishi units do not support Car Play or Android Auto.  The latest Panasonic units can support Car Play and Android Auto - but it is not clear when the NTG5*1 Panasonic units started supporting it.  The NTG5*2 Panasonic units seem to all support Car Play and Android Auto.

The NTG5*2 vehicles with Audio-20 have the option code 154 when they have Panasonic units.

If you need Apple Car Play retrofitted, I suggest you contact Comand (Europe) Ltd / Unique Car Sound who have the genuine parts and Diagnosis systems to install factory Car Play properly.

Option Codes

These are the option codes for the various systems.
