Does anyone else have a problem playing .WMA encoded CD's in their RL. I can play .MP3's but when I insert a WMA CD, I get an error message "no disc" , and the disc is ejected. A couple of days ago when I was getting my rear differential oil changed (in my 05 RL), I brought the same CD with me and tried it on a new 06 RL, and it worked fine. I've got an appointment in two weeks to replace the radio. It seems strange that an MP3 CD will work, but not a WMA!!?? By the way, the WMA compression is about twice that of a MP3, so I can fit more songs on a CD with no noticable deterioration in sound quality.
