Hi!

I have changed the original audio 20 head unit to NTG 2.5 in my W211 2003 it works and its good but I can't use the aux input. I bought this cables for the head unit: http://www.kabeldaviko.de/product_in...r-ntg-2-5.html

the guy who helped me, told that I have to enable the aux input in engineering mode, but I couldn't find anything about where can I found it in the engineering menu. :nix:

As you can see in the tutorial you need to know which module you are connecting to and have the descriptor file for it.
Basically you want to follow the tutorial until you open the variant coding screen, you can then print out that screen.
