Hi all I'm after some help if poss The stereo in my 323i se e46 2000 is not playing CDs from the changer in the boot The changer slides the individual trays in but when I change format to cd it states no disc and the numbers just change the radio station !! The stereo is the business system model . Has anyone had this problem and is there an easy fix ? Also I have an iPhone 4 s and would like to integrate into stereo system as I use Spotify for my sounds any ideas on kits ? many thanks
