COMAND ONLINE ntg4.5 vs ntg4.7 ?
I thinking to retrofit E250 2014 from Audio20 to Comand Online
Does anyone know what is the different between NTG4.5 & 4.7 ?
What is the Yellow (4pins round connector) at the back of NTG4.7 for ?

Thank you guys

There seem to be a few 4-pin interfaces that are different from the earlier model.
