If you enable AUX in 7.7 HU Parameters , then UCI in 7.5 TGW will show not installed and grayed out which is Media Interface, correct settings for me to get sound, satellite radio and media interface back was as follows:

7.7 HU Parameters - AUX - Not Installed
then go to:
7.5 TGW Parameter
Most - ON
Audio Source - External Amp
DAB - not installed
SDARS - installed (this is satellite radio)
UCI - installed (this is Media Interface)
TV Tuner - not installed

then perform a 9.1 System Reset
In my menu NTG Menu then I had both Media Interface and AUX after this, my MI cable connector has both a 3.5mm input cable and Ipod cable, if connect to the 3.5mm I select AUX in my menu, if I want to use my IPOD I select Media Interface.

Hope this helps, save time for some.

Hi
you made a great job!
Do you know if exist a method (in the engineering menu) to restore the default navigation maps? I've no any DVD or SD with original maps.
Thank you lots!

Hi, Thanks for the information on engineering mode. It is very useful.
I am trying to enable Audio AUX input. From what I understood, the only thing I have change is change Audio Source - External Amp. and restart?

Currently my 7.7 HU Parameters - AUX - Not Installed and grey out. Will this fix the aux input?
I have attached the current setting here.

Hope you can help.

Hi everyone!
I am one of the lucky ones by owning a brand new MY13 ML350 4Matic (W166). After reading some comments about COMAND ONLINE, I've decided to discover it myself. I was able to get into the engineering mode by "end call + 1 + #" key combination pressed for about 10 sec. There is also another secret menu after entering the engineering mode as mentioned in some threads in this forum. I managed to enter the second menu with the key combination "end call + 4 + #" after entering the engineering menu. I prepared an instruction with screens from COMAND ONLINE in the attachment for those who wants to bring some cool features on to their COMAND system. I must warn though, you can mess up with your settings. So, don't change anything if you are not sure what you are doing.

Good Luck

Can I resurrect this thread and ask if there is anything in the engineering menus to fix my TV split screen.
The TV fades as it should in motion but when I switch to split screen for the passenger that side defaults to "Mercedes APPS" whilst the driver sees the warning display.
Thanks

Dear all
I have x166 and missed up the settings.. Unfortunately the sound had gone completely when I select Aux Audio or Aux video, although my amplifier settings is set to External and Aux enabled and Most is ON.

Any clue how to reset entire menu to default or solve this problem

Do you have a working version of Vediamo and know how to find the correct .CBF to communicate with your COMAND unit? If so its pretty easy to walk you through it, if not let me know when you get the hardware and software.
