My 2002 ES 300 has had problems with the CD changer for a long time. It will not go from disc to disk without giving the error 3. Once, it plays a cd, it is fine. It just has problems loading , unloading, and going from disck to disk. What have others done in this case? I called a Lexus dealer and they recommend a refurbished one as an exchange . I have the Levinson system. Any thoughts or suggestions are appreciated. Stephen
