Hello, I recently bought a cable for my radio from this link http://allegro.pl/kabel-zlacze-adapter-sygnalowe-aux-alpine-jack-3-5-i6678457896.html I connected to the radio, but I don't know how to run it in on the radio because after connecting, for example, a telephone to the cable, nothing happens. Anyone know how to switch on the radio to activate it? I am asking for help, thank you in advance and best regards
