I have read that when using an external device - USB stick or Ipod etc it can take a little time to read all the info - however next time you connect the same device if nothing has been changed it will read the info a lot quicker. wife has copied across music from Itunes onto memory stick and has not reported any problems using it. Also with the quick play I have had with the system I really like the controls built into the steering wheel - a lot easier to use then on a stalk like they were in 207. Changing radio station is really easy with the list and scroll wheel option.
