The 2004 radio has text capability so you can add Sirius or XM and get the radio to scroll artist and song title. Beginning in 2005 the X5 business radio had MP3 capability but does not display ID3 tags just TR01, etc. So if you want to play a CD with MP3’s you can get the newer radio or get the newest (2006) 6 disc MP3 changer. It will play MP3 CD’s on your current radio with no ID3 tag info.
