I guess a CD changer is as dead as a do-do nowadays. I think I've only used mine once in nearly a year now. Just can't be bothered.
Being able to play my iPod after downloading on the computer so many tracts is fantastic!
In my last Beemer the muli-changer was an important 'extra' and sort after. I doubt on new motors if BMW can give them away now.
How times change!
