Introduction
Your radio system also has a CD function that operates exactly like
a normal CD changer. An audio CD or MP3/WMA CD is inserted in
the CD changer ⇒ page 29. You can also play a SD/MMC memory
card with MP3/WMA files. You can choose individual tracks of a CD
or memory card, play the tracks in any order, or just listen to each
track for a few seconds.
