hi all,

I have W204, 2013 with Audio20. I want to upgrade my command with better NTG 4.5 system and bigger 7" screen which I know that is possible. My question is, if it is possible to upgrade also to NTG 4.7 ? Have anyone tried this before?

For what I know that we need is:
Monitor, Zentraldisplay Teilenummer: A1729008500, you can find it also like A1729016500
Abdeckung Kombiinstrument: A2046890039,

Abdeckung Oben: A2046890639 (You can probably use the current frame),
Abdeckung Unten: A2046890839 (You can probably use the current frame).


I've been told that COMAND needs the fans. Audio 20 does not. Is this true? Do I need to buy also axial fun with air ducts?
Thanks.
