As you have often discussed, there are difficulties with the Volvo radios and mp3 files. I like listening to audio books that are available on CD in mp3 format until now. If there is no easy solution (adaption of an external device to the control unit from the CD changer or the like) then I would make the effort and burn the audio books to CD-RW (Harry Potter, Volume 5 = 27(!!) CD’s :-). If any of you have with the new generation of Volvo devices (Harry Potter, Volume 5 = 27(!) CD’s :-). already had corresponding experiences and can therefore tell me whether these CD-RWs can play? Greetings from Stefan
