Dear we47b1me,
yes I know that I have to do a complete retrofit; I have already bought all part for this. The only information I'm missing right now is how to repin the quadlock but I am searching it and I think I will find it in WIS. When I found it and finish retrofit, I will share with everyone.
If someone could help it could save me time.
Thank you very much!
Kind regards

it's a different wiring harness. Chris The Swede did this last year. There's a whole step by step on YouTube.

For Comand NTG5s1, I think that
1 = ?
2 = Night Vision ?
3= GPS
4= BT
5= LAN
6= AV out ?
Blue = Display
White= Rear view Camera
Black= USB

Could someone please confirm and help to identify number 1, 2 & 6 ?

Thank you very much!

COMAND NTG 5s1 retrofit on ML350 W166 NTG4.5 Audio 20

Hello everyone,
I am currently doing the COMAND NTG 5s1 retrofit on my ML350 W166 initially equipped with NTG4.5 Audio 20 (1CD).
I share my work with you. You may also find this useful.
I think that the most important is the repinning of the Quadlock. After a long search in WIS, I identified most of the pins.
Here is the original NTG4.5 Audio 20 quadlock :




















NTG 4.5 Audio 20 Quadlock scheme

For A2 and B blocks I am sure of the pin identification:

Does anyone know what pin number 14 is for in NTG4.5 Audio 20 ? And in Comand NTG 5s1 (Wake up, USB Splitter ?) ?
Should I leave pin 14 (30g 0,35 RDBK) in place for Comand NTG 5s1 ?
For Comand NTG 5s1 WIS indicate Mute 0,35 BUBK for pin 9, what is it for ? In my Audio 20 this pin does not exist, so what I have to do? leave pin 9 empty ?




So you have to move following pins in Connector B (white): pin 2 (Mic Shield, 0,35 BK) to pin 3 , pin 7 (Mic 2+ 0,35 OG) to pin 2 and last pin 8 (GND 0,35 GN) to pin 9.
I still have some doubts for some pins of block B: in my NTG4.5 Audio 20 I have an auxiliary input in the center console, so I think pins 4, 5, 10 & 11 correspond to Aux input.
But with Comand NTG 5s1 I will no longer have the auxiliary input. So should I leave pins 4,5, 10 and 11 in place ?
For Comand NTG 5s1 WIS indicate: pin 4 = Mic + and pin 10 = Mic (-); what are these pins for ? are they really necessary when upgrading NtG4.5 Audio 20 to Comand NTG 5s1 ? What I have to do ?

Last question concerning block B: for NTG5s1 WIS indicate pin 7 = Cradle_comp (0,35 BUBK); what is it for ? what I have to do ?

Now let's go to block C (black 12 pin connector):

Despite several searches in WIS, I did not find what the pins number 3, 4, 5, 6, 10 and 11 correspond to in my NTG 4.5 Audio 20.
Could someone please help to identify them
so that I can apply the necessary changes to the Comand NTG5s1 pins?

For Comand NTG 5s1 WIS gives the following wiring for 12 pins black connector C:

By examining the diagrams of blocks A2, B and C, you see that it is necessary to make the following modifications:
a. move pin A2-9 (CAN B L 0,35 BN) to pin C-3
b. move pin B-6 (CAN A L 0,35 BN) to pin C-4
c. move pin A2-11 (CAN B H 0,35 BNRD) to pin C-9
d. move pin B-12 (CAN A H 0,35 BKWH) to pin C-10
e. add cable 1.3 of Fan M4/13 (additional fan for COMAND) to pin C-1
f.
add cable 1.4 of Fan M4/13 (additional fan for COMAND) to pin C-8

Pins number 5,6,7,11 & 12 are related to Diag connector X11/4. I think I don't have these pins in my NTG4.5 Audio 20; so what I have to do ?


With these modifications I managed to get my Comand NTG 5s1 to work:



I continue to look for the missing information and will keep you posted as soon as I have any news.
Thank you in advance for your help
Kind regards

you're going to run into compatibility issues out the wazoo. Hence my previous comments.

Dear we47b1me,
yes it is possible but should I give up so far ?
I don't think it's impossible because several people have already done it.

And you, did you do a Comand NTG 5s1 retrofit ?
Thanks

if you're just swapping pins, it will not work. Not everything will function properly, you have to do a full h/w swap like chris the swede did. I didn't want a comand 5 retrofit. I wanted the android tablet retrofit which was easier, allowed me to customize the screen, add apps, and still retain full comand when I switch back to that side. It's, in my opinion, better than the comand system.

Hello,

There are still some Problems:

1- there is no sound from the speakers; however block A1 is 100% identical between NTG4.5 Audio 20 and NTG 5s1. Do you have an idea why there is no sound?

The volume control (by +\- and volume button on the comand) does not work either.

MOST is desactivated, so it should have sound.

What can be wrong?



2- Radio does not work, I have the following message on screen: “FM/DAB radio, device unavailable “ however the antenna cable is well connected.

what can be the problem?




Thank you very much for your help.
kind regards

I have identified two others connectors on NTG 4.5 Audio 20
Number 2 (pink) is for USB & Aux
Number 4 is BT

So only number 1 (green connector) remains to identify.
Could someone please help to identify this green connector ?

Thanks

That's because the w166 did not have a motorized reverse camera. It was fixed. You're going to need to do some trial and error, and likely have the positive lead for the motor flap to be tied to the trigger 12v that engages the camera.

Thank you very much we47b1me !
if I understood correctly you have to connect the cables directly to the power supply (reverse light ?) and to the ground ? not to Quadlock ?
Thanks !

I don't understand.

Like I said you need to play trial and error.

And you still obviously need to get the video signal up to the COMAND unit.
