Has anyone managed to do this via the extternal input on these radios. Becker make the radio but the correct lead is hard found. the mp3 Actros has an input on the front unfortunately i have the older mp2 radio.
i’d also like to know this, i have mp2 actros and radio has aux input function but can’t find any input plug, also in handbook it says you can connect mp3 or tv through radio, had radio out and can’t see owt
had a mp2 myself couldnt find the aux either bought a pure highway to give me dab radio it works on a frequency set the highway tune the radio you have dab radio it also has a input for ipod so you can run that as well 
on my old sony MD radio theirs an input on the rear of radio
just slide it out and have a reccy
just an idea
