Looking for some help on playing music from a USB key in the centre console from iDrive (2010 idrive).

I have a full 16G USB key, and each time I start the car, iDrive takes about 10 minutes to index the USB key before displaying the available music files for playback.

Does everyone have the same problem, or is there a way to do this so that iDrive doesn't re-index everytime? I'm downloading music files to the USB key via windows media player.

I won't bother with the idrive hardisk if I can get this working without an extended delay each time I start the car.
