Yes I am excited about this. Our 03 X5 now plays MP3s using a BMW CD Changer.
This thing ROCKS! When you go past 99 songs. 99 is shown as 1-99, 100 is marked as 1- and then 101 goes to 1-01. I guess this is because my radio only knows of a possible 99 tracks. It is interesting that it plays over 100 tracks and restarts the number.
