I have a 1993 BMW 325i and the CD changer is no longer being recognized by the Head unit. I have looked all over the Web with no help. The changer still loads and responds as always, just that when you hit the band button to toggle from FM to AM to CD the CD never shows up. I have reset and removed battery power, Still nothing. I did not install the Changer. The Head unit shows Alpine3 and the changer is a Pioneer CDX-M30 . Is there a trick to get the head unit to recognize the Changer?
