Nope
For some reason, 5+ (7+?) year old MP3 technology is considered unimportant or too new and too high tech for the XLR, even tho it would expand the CD changer from 6 albums to 60 albums (who would want that?).
:banghead
As I've said before, I'd trade the useless voice recognition system for the ability to play mp3's in one second.
:nopity
Of course to upgrade the CD changer would be difficult, if not impossible with all of the computer integration of components...
I'm sure we can count on Cadillac & GM to engineer a replacement module for a few hundred dollars to enable MP3 capability (yeah, right!!!). If you believe that, I've got an excellent, VERY profitable bridge for sale, it goes from Manhattan to Brooklyn--just email me if you are interested.
:glol
I wonder if the Viper RT-10 or the Ford GT40 (my Feb 08' XLR replacement????) will play an MP3. By then it will HAVE to be standard equipment on any car over $30K (unless the music companies own the car companies

.
Annoying as it is, I still love my XLR--4 days till' Spring in NY, Yabadabadoo, here comes top-down, 4 wheel drifting weather! :reddevil
