Technical CN+ Navigation in the order / Radio does not work ( RADIO OFF )

[scWojtek]

Hello
I
buy fiata stilo abarth the radio does not work in him ?
Navigation works all accessible options but the Radio OFF .
does someone know the cause ? the reason ?

the Radio is in the hidden menu on in red .

The aerial has the full range ( on green )

Is it only the radio? or is it all of the audio functions?

If it's all audio functions, press the " AUDIO " button for more than 2 seconds.

The functions of the radio are not active on grey . Keeping the button does not help.

Such subject was some day with pictures here someone inserted but I can not find him
