radio engineering mode
it comes from standard radio cd/player, no cd changer in glove.
I think it's called audio 20.
does any way to get into the engineering mode of the radio?
I'm looking for parameters, trying to play mp3.
I've heard about the head unit doesn't play mp3s, only the cd changer does, but maybe there's some configuration parameter in the engineering menu that can help !.
any information about it will be appreciated,
regards,
