I've recently got a new A3 company car with the standard single CD head unit (no multi changer). I'm looking for some way of playing MP3's in the car (I've got hundrerds of CD's albums and singles). Ideally I would replace the head unit with one that took MP3 CD's, but don't think I wouild be allowed by "the company" I could add an audi changer, but I don't think that would play MP3's and don't think it would show the album, track name, etc. Other option is Ipod linked throuigh radio. Any other good suggestions to avoid me carrying around hundresds of CD's?
