Have read other posts but none have worked for me so far

press menu only gives cd not aux  can not find aux  on/off  in settings ?

Press the Media button and the option should be in there.

Unlike the new Fabia there isn't a on/off option, as Tween said hit the Media button, there should be "Radio CD Aux" or something along those lines, no need to activate it

 

P.s, for future reference if you have any other quires I'd post into the Citigo section as oppose to the Technical section, you'll get a faster response as not many view this section
